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

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.

Move jsdoc comment closer to the methods they are describing. This also
enables better typehint support.
I36b3ae7f9f633877683bc17a9444c970d7fa7293 will handle revising tableOfContents.js.

Given our use of constants for tracking classes this eslint rule
is more an annoyance than helpful.

Rather than test for fetch, limit the code to ES6 browsers.

Given that these styles deal with the layout of the sidebar button in
the main header and don't make sense in any other context (at least
currently), I think they belong in Header.less.

We want the link that the user has clicked inside the TOC to be "active"
(e.g. bolded) regardless of whether the browser's scroll position
corresponds to that section. Therefore, we need to temporarily ignore
section observer until the browser has finished scrolling to the section
(if needed).
However, because the scroll event happens asyncronously after the user
clicks on a link and may not even happen at all (e.g. the user has
scrolled all the way to the bottom and clicks a section that is already
in the viewport), determining when we should resume section observer is
a bit tricky.
Because a scroll event may not even be triggered after clicking the
link, we instead allow the browser to perform a maximum number of
repaints before resuming sectionObserver. Per T297614#7687656, Firefox
wasn't consistently activating the table of contents section that the
user clicked even after waiting 2 frames. After further investigation,
it sometimes waits up to 3 frames before painting the new scroll
position so we have that as the limit.

The behavior of data loading can differ between submitting and display,
so use FauxRequest to customize the method.
Also fix the order of parameters passing to assertSame(), the first one
should be the expected one.
