As it turns out, anchor links on headings only worked on our /help and
/api pages but were broken everywhere else. This commit adds the
required JS to scroll properly when an anchor link on any of our
various landing pages is clicked. We already have similar code to
accomplish this in help.js.
We verified with console logging, browser Sources inspection, and
checking source files that help.js and landing-page.js are never
included in the same page, but we add comments to make this
architecture clear.
Fixes#19349.
SimpleBar 6.0.0-beta.2 through -beta.6 are built with ES6 syntax (I
assume inadvertently: https://github.com/Grsmto/simplebar/issues/523),
and its latest tag has moved back to 5.2.1 anyway.

Previously the title for all pages of the user and API documentation was
just "Zulip", which does not only bad for UX but also for accessibility.
We were already extracting the title from the Markdown for the og:title
tag, so we just need to set the <title> tag.
Since our documentation fetches pages with Ajax if you have JavaScript
enabled, we also need to save the titles in the article cache.

Not having a focus outline is very bad for accessibilty.
Browsers have it by default but we completely disabled it for links in
the sidebar in 9955580251.
Showing the outline when selecting a page in the sidebar can be
distracting, so we hide the outline for the highlighted sidebar link.
Since every focusable element however should have a focus outline, we
make the highlighted link unfocusable by setting tabindex=-1 (which also
makes sense since the link to the current page doesn't do anything
anyway).
Part of #15948.
Three reasons:
1. The sliding was disorienting.
2. The collapsing disallowed searching for other pages with Ctrl+F.
3. The collapsing mechanism wasn't accessible (not usable with the
keyboard / no ARIA tags).
Tweaked by tabbott to center the left sidebar on the selected page.

Prettier would do this anyway, but it’s separated out for a more
reviewable diff. Generated by ESLint.

Apparently, our scrollbar logic crashed with an invalid URL fragment
(hash), which resulted in initialization not completing and thus the
logic failing.
In my view the root issue here is that we're not doing a good job of
catching JavaScript exceptions in portico pages.
Fixes#15706.
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`. It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

We were using these hollowed out arrows characters (⇽ , ⇾) in a few
places, these were inconsistent with the solid up and down arrow
characters (↑ , ↓) we use otherwise. This commit replaces them
everywhere in the codebase.
Currently, if you access an article link with an anchor link that isn't
featured in the sidebar, the main article won't be highlighted. Thus, we
exclude the anchor link hash from the article-searching selector if
the full article pathname wasn't found.
When you hover above the navbar, the cursor focuses on the page
body and scrolls the entire page, breaking the positioning of the
fixed sidebar and page content.
We disable scrolling on the body but allow the sidebar and Markdown
content page elements to be scrolled to fix this bug.
Whenever a link is clicked, the page link changes, and the content
of the `.markdown .content` node updates, preventing the old
listener to catch any future anchor link clicks.
We attach the listener to the document instead and only activate
it when the target element is a proper anchor link heading.
Fixes#9767.
We should only open the default article heading which is "Guides",
if the user is on the index page i.e. /help/. For non index pages
we don't need to open this heading.
This commit adds a minor improvment in clicking
the left sidebar behaviour. So if you click on
an article heading then other opened headings will
be closed automatically. This makes the toggle
experience better.
This is preparation for enabling an eslint indentation configuration.
90% of these changes are just fixes for indentation errors that have
snuck into the codebase over the years; the others are more
significant reformatting to make eslint happy (that are not otherwise
actually improvements).
The one area that we do not attempt to work on here is the
"switch/case" indentation.
Update perfect-scrollbar to fix stutter space-scrolling in #8544. Also
reworked deprecated `element.perfectScrollbar` to `new
PerfectScrollbar(element)`. Lastly, updated provision version and
changed node module path to new path.
This also refactors perfect-scrollbar in help.js to work with updated
version of perfect-scrollbar. Because the update also changed
perfect-scrollbar's css selectors for all scrollbars in zulip, we
update those too.
Fixes#8544.
