The `Node.nextSibling` property returns the next Node, not the next
Element. If whitespace, an HTML comment, or any other type of
non-Element Node is ever introduced between the Elements then
`.nextSibling` no longer returns the desired Element. Switching to
`Element.nextElementSibling` would work, but finding the Elements by
ID is more readable and future-proof.
Move server message queue processing out of `handleUserChanges()` for
the following reasons:
* Fix a race condition: Before this change the client would stop
processing incoming messages and stop sending changes to the
server if a `NEW_CHANGES` message arrived while the user was
composing a character and waiting for an `ACCEPT_COMMIT` message.
* Improve readability: The `handleUserChanges()` function is for
handling changes from the local user, not for handling changes
from other users.
* Simplify the code.
Safari takes a while to initialize `document.styleSheets`, which
results in a race condition when loading the pad. Avoid the race
condition by accessing the CSSStyleSheet objects directly from the
HTMLStyleElement DOM objects.
* code tidy up: always evaluates
* tidy up: is always true
* tidy up: remove unused code
* always true/false variables
* unused variable
* tidy up: remove unused code in caretPosition.js
* for squash: Revert "tidy up: remove unused code in caretPosition.js"
The `if` condition was previously always true, so the body should be
preserved. If the body is preserved, other logic can be deleted. I
opened PR #4845 to clean it all up.
This reverts commit 75b03e5a7d.
* for squash: simplify
* for squash: Explain that the getter is used for its side effects
It's very weird to call a getter without using its return value. Add a
comment explaining why this is done so that the reader doesn't get
confused.
* for squash: Revert "tidy up: remove unused code"
The exception test was the purpose of the code.
This reverts commit 85153b1676.

This also makes the full line number element clickable to ensure a positive UX for the ``?lineNumber`` URL endpoint. It also makes it more obvious that a click action can happen based on the hover.
Make line numbers stick to baseline of first line of wrapped content and editor lines with increased line hieght.
Make it compatible with ep_author_neat
