Without this a border is set in all directions.

Since [1] PDF.js does not dispatch events to the DOM any more. Therefore
the client needs to listen for the `documentloaded` event from
`PDFApplicationViewer.eventBus`. The `eventBus` property is only
available once the viewer is initialized, so the client needs to wait
for `initializedPromise` to resolve before checking it.

 - Remove the IRC links since no Hypothesis staff engage with IRC any
   more as far as I am aware. We do monitor Slack however.

 - Update the Google Groups URL for the dev mailing list to point to the
   new version of Google Groups which (finally!) no longer relies on
   fragment URLs

The newest react-hooks ESLint plugin correctly reported an issue where
a `useLayoutEffect` hook had a dependency on a value which changed on
every render.

This property was not implemented when the annotation body components
were converted from Angular to Preact.

 - Add `textStyle` prop to `MarkdownView` and `MarkdownEditor` which
   sets additional CSS properties to apply to the rendered annotation
   body
 - Read the theme style properties for annotation bodies in
   `AnnotationBody` and pass the resulting `textStyle` down to
   `MarkdownEditor` and `MarkdownView`

If minifying code that does not contain an inline sourcemap, don't set
the `sourceMap { content: "inline" }` Terser option to read that
sourcemap. This affects a subset of all the vendor modules that are
included in the Hypothesis client build.

Adapt to the `minify` function becoming async.

These are replaced/consolidated by `FilterStatus`

Update `forcedVisible` to use only `$tag` values, not
`id`s.

Don't clear selection (filters) when a user creates a new
annotation or reply. Instead, force the new annotaiton/reply
visible and make sure that forced-visible threads are
honored during thread-building.

Fix the `ctaBackgroundColor` theme property not being applied properly
to the drop-down arrow on the right-hand side of the "Post to <group>"
button.

Fix an incorrect call to `applyTheme` which passed an invalid theme
property name. This is a regression from when this component was converted
from AngularJS to Preact in 7bbb8a60.

Also improve the type definitions of `applyTheme` and add a test to help catch
such mistakes in future.

Make it easier to explore all the code and resources that make up the
development server by putting them all in one directory.

Replace the index page of the dev server with a more useful landing
page. The iframe has been removed because it is something we're not
testing most of the time and there are remaining issues with the way
multiple frames are supported in the sidebar. A separate test document
can be added for this purpose in future.
