This code is not resilient to changes in the mw-ui-icon definition
In preparation for changing touch areas we need an easy way to
flush these correctly based on feature flag.
No expected visual changes.

The table of contents has since been reflected to
not use calc statement anymore and pre-calculate the value,
cssjanus flips this value properly so this rule can safely be removed.

Pixel shows 15 regressions, these are expected changes that are
fixing issues on specific viewports that fixes the following:
[At exactly the tablet breakpoint]
* the more menu dropdown was being
shown at the same time as the other menu items, resulting in duplicates
(see https://phabricator.wikimedia.org/F35285379)
[At exactly the desktop breakpoint]
* The table of contents AND the
table of contents toggle button to the left of the title were showing
(see https://phabricator.wikimedia.org/F35285392)
* The sticky header was not showing
* The fly out table of contents was showing instead of the sidebar
table of contents on scroll
* The top of the sidebar is brought into alignment with the tabs
(see https://phabricator.wikimedia.org/F35285408)

Previously, we relied on setting pointer-events:none on all child
elements of ToC links.
This propagated the click event up to the link itself in Javascript
and allowed us check if an element with the class `.sidebar-toc-link`
was clicked.
Unfortunately as of Chromium 101 this approach causes the entire link
in the sidebar to be unclickable.
Instead, this patch checks if the ToC link or any of it's children
have been clicked (using the less efficient `Element.closest()` ).

- If TOC A/B test is enabled, page is in treatment group, and
viewport is below tablet, force legacy TOC to render.
- If TOC A/B test is disabled and new TOC feature is enabled,
and viewport is below tablet, neither TOC should render.

This uses the sticky header's `.mw-sticky-header-element` utility class
to conditionally offset the table of contents to the height of the

Collapses sub-sections in the new table of contents by default
(except for non-js and reduced-motion users) and expands the
sections when the top-level section link has been clicked.
Refactors the `activateSection` TableOfContents methods into separate
`activateSection` and `deactivateSection` functions.
Adds `expandSection` and `collapseSection` methods.
Adds triangle icon as a visual expand/collapsed indicator
next to all ToC section headings and are hidden via CSS based on
whether or not the section contains subsections.
Adds test for tableOfContents.

This commits sets up the Table of Contents to bold the active section
when the section is scrolled.
Unfortunately, because our content does not have actual sections but
instead has a flat list of headings and paragraphs, we can't use
IntersectionObserver in the conventional way as it is optimized to find
intersections of elements that are *within* the viewport and the
callback will not reliably fire during certain scenarios (e.g. with fast
scrolling or when the headings are not currently within the viewport).
Furthermore, iterating through a list of elements and calling
`getBoundingClientRect()` can be expensive and can also cause
significant forced synchronous layouts that block the main thread.
The best compromise in terms of performance and function that I've found
is to use a combination of a throttled scroll event listener and
IntersectionObserver's ability to asyncronously find the
boundingClientRect of all elements off the main thread when `.observe`
is called which is the approach this patch takes. Although this is an
unorthodox way to use IntersectionObserver, performance profiles
recorded while holding the "down" arrow and scrolling for 10 seconds
with a 6x CPU throttle are comparable between master and this patch:
