Now it's possible for this to run twice, keep track of whether

more than once.

Removes the permanent scrollbars from Vector 2022
as well at the 100% height on `.mw-page-container`.
The permanent scrollbars ( overflow-y:scroll) are
an artifact of legacy Vector and no longer serve
a (known) purpose.
The 100% height on `.mw-page-container` was originally
added to fix T257518, however that fix is no longer
necessary with the use of CSS Grid for layout.

Refactors the bottom border in the zebra update
so that it doesn't require flexwrap on the
`.vector-page-titlebar` element, which can cause the
PagTitlebar layout to break when the page title is
longer than one line.
The challenge with the underline in Zebra is that we
want to use padding to create the white background on the
content elements, but we *don't* want the underline
to stretch to edge of the box (which is what bottom-border
or box-shadow would produce), instead we want the
underline to only span the width of the content.

In 3cea6d41, files were split between the zebra/non-zabra modules

- Moves common variable and mixin imports from

This change scopes the styles related to the Zebra
update by wrapping the imports in a top-level feature
flag selector,
i.e
.vector-feature-zebra-design-enabled {
@import "./screen.less"
}
To account for this extra selector, ampersands are
added wherever the html element is targeted in the
affected files. This applies to both zebra enabled
and disabled files.
getDefaultModules() is used in SkinVector22.php to
conditionally load the new skins.vector.zebra.styles
module when the feature is enabled.

Change-Id: I9b367ca0a0afea32b49915b40bc03c05910d4227
This refactor seeks to make it easier to separate
feature flagged styles by wrapping the imports in
a top-level feature-flag selector, e.g:
.vector-feature-zebra-design-disabled {
@import './layouts/preZebra.less';
}
This change does the following:
- Moves all file @imports to skin.less
- Removes unnecessary @import from MainMenu.less
- Moves .mixin-page-container() to mixins.less
- Moves @min-width-supported variable to variables.less
- Scopes existing Zebra styles at the skin.less file @import level
- Removes selectors ending with ampersands
The last changes makes it easer to reason about changes
specifically when wrapping entire file imports in a selector
since the ampersand ends up inheriting its value
from the skin.less file.
No visual differences are expected with this change.

I04f9e48a1cf9dee915cf51e1e12b17ff0a595a06 provides neutral values for
the Codex tokens in mediawiki.skin.defaults.less in MW core, and expects
skins to import the appropriate Codex themes in their
mediawiki.skin.variables.less.
For both legacy Vector and Vector 2022, import the Codex tokens for the
wikimedia-ui-legacy theme. We need to use the legacy theme because
Vector and Vector 2022 have a base font size of 14px; the non-legacy
theme assumes a base font size of 16px.
Remove some variable assignments that are now redundant, because their
values are the same as the Codex tokens we're importing.
After importing the Codex tokens, override some of their values where
necessary so that all variables' values stay the same(*). We should
consider whether to remove some of these overrides in a follow-up patch,
but keeping everything the same for now makes this change less
disruptive.
(*) As in the core change, one variable's value does change:

Per T325086, the TOC should expand and activate the section that corresponds to
the window's hash fragment.
Additional changes:
* Moves logic that runs on page load to determine the
intersection from section observer to main.js, since the hash fragment can
take precedence over the scroll position (e.g. when scrolled all the way to the
bottom).
* Make section observer's pause() cancel any pending intersection calculations
so that it doesn't interfere with other async logic.
* Moves onHeadingClick and onToggleClick logic to activate and expand a section
to tableOfContents.js to facilitate unit testing this behavior with clicks and
hash fragment changes.

__Template__
The template is not particularly useful - it is only ever
used once in this context and features a static ID which means
it can never be reused. It is also tied to the #vector-toc-collapsed-checkbox
element. In current form it doesn't make sense to have this template.
Maybe in future, I could see an argument for a PinnableTableOfContents component
that wrapped the checkbox and nav element, and generalized the IDs but
currently there's no pressing need or value for that.
__Layouts__
The existing Pinned and Unpinned stylesheets are concerned with how the table
of contents is layed out holistically with regards to other components and
features enabled on the page. I think these should therefore be organized as such.
The way I reason with this, is these styles would be irrelevant in a component
library if the component was rendered in isolation.

* When wikipage.tableOfContents is executed, the table of contents has been

observer as the old sections no longer exist in theDOM.
* If VisualEditor repaints the page, we should update the elements associated

* When VisuaLEditor is active we should disable the intersection observer as
there is no table of contents to update.
Minor changes:
* Light refactor of large function in main.js
* reloadTableOfContents returns a promise and now fires a new hook
wikipage.tableOfContents.vector to signal when it is finished which
has also been requested by community members. This allows the code in main.js
to update elements at relevant point in time
* Add FIXME note (doing this would have been considerable work)

Rather than try to build individually build login, logout, and create account menu items, we handle them the same as all other user links menu items in Hooks.php. While Hooks isnt ideal, there currently isnt a good path for moving that code to SkinComponents until core provides menu data. In the meantime, this patch reduces code complexity and prevents bugs like T324638.
This approach also allows us to move user links logic from SkinVector22 to VectorComponentUserLinks.php, and ensures the user links dropdown contains multiple menus, which allows us to reuse styles from page tools dropdowns.

Follow-up to 886437, which suggested moving the bottom padding of the scroll
indicator's parent to the `mixin-vector-scroll-indicator-mixin`. This makes
sense because if the correct amount of bottom padding isn't applied, the scroll
indicator could overlap the text when scrolled all the way to the bottom.

Use CSS to decide whether to show the button or not. This retains the
existing logic for hiding the button on any page where the action is not
view.

The TypeaheadSearch component in Codex switched from using content-box
to border-box for the dimensions of its menu items, reducing their
height by 2px (because of the top and bottom border). Update the
height calculation for the loading indicator accordingly.

Overrides the `wikibase.client.init` module to
better style the interlanguage link button in
Vector 2022.
Also adds the `.mw-list-item` class to that link
so that it maintains consistency with the other
menu list items.

Only do this when JS is enabled and the Vue search (Codex
TypeaheadSearch) is going to be loaded. Without this, when viewing
Vector with an increased browser font size, Codex's icon scales up but
ours doesn't, causing the icon to grow and jump when Codex loads.
Set the icon's size in relative units (em instead of px), and change the
background position so it stays in the same place.

This reverts commit 45247802db.
Reason for revert: This is causing the TOC button to become focused on page load

No longer needed now that the underlying cause has been fixed.
This reverts commit 5bcc1597ca.

Clicking the bolded text in the search footer didn't work. This change
fixes that by working around the underlying issue, rewriting the search
footer template to use v-html instead of v-i18n-html. I don't know
exactly know why this works, but it does. Hopefully we'll be able to
fix the underlying issue and undo this workaround in the future.

Move feature classes to HTML element - this is significant
for anonymous as placing the classes on the body tag breaks
the browser's ability to parse the article concurrently
with the stylesheet download, because inline scripts
are spec'ed to be able to see document.styleSheets.
Changes:
* Feature classes are moved from BODY tag to HTML tag
* For now disable localStorage storage until we've worked out
the storage mechanism in core.

In production this is always true, so remove feature flag.
Retain A/B testing code in case it is still needed.
