Before the introduction of the `renderRichText` helper function we
exclusively used `this.#html` for XFA rich text and exclusively used
`this.#contentsObj` for plain text. However, after the refactoring we
tried to access `this.#contentsObj.dir` in both cases, which fails for
XFA rich text because `this.#contentsObj` is `null` in that case.
This commit fixes the issue by using optional chaining to make sure we
don't try to access non-existent `this.#contentsObj` properties, which
makes the `must update an existing annotation and show the right popup`
freetext integration pass again.
Fixes#20237.
Fixes 35c90984.
If the document changes the comment state from the old document should
be replaced with that of the new document. To do this the comment
manager is destroyed, but the corresponding comment sidebar wasn't
destroyed yet, which resulted in the comment state from the old document
still being visible for the new document.
This commit fixes the issue by hiding the comment sidebar if the comment
manager is destroyed. Note that hiding the comment sidebar effectively
destroys all its state, and we already set the annotation mode to "none"
on document change so we don't want to keep showing the comment sidebar
anyway.
This function is required for the commenting feature: the user will be able to click
on a comment in the sidebar and the document will be scrolled accordingly.

The exact selection can differ a bit per OS/browser. In this case the
last character was consistently not selected while on other platforms it
is, so this commit fixes the issue by relaxing the regex to not consider
the final character so that the test passes if the rest matches.
This removes the following error from the integration test logs:
```
JavaScript error: http://127.0.0.1:59283/build/generic/build/pdf.mjs, line 3879:
TypeError: EventTarget.addEventListener: 'signal' member of AddEventListenerOptions is not an object.
