Ref T12616. When you "Delete" a comment from the preview, we try to delete the comment on screen too.
It may or may not be present on screen: if you just added it it's usually visible. However, you might also have hidden the file it contains or it could be on an older diff in a file which is no longer present in the current diff.
After updates in T12616, we could only find the comment if you'd previously interacted with it for some reason. Update this code to be able to find all inlines present in the document.
Test Plan:
- Write a draft comment.
- Reload the page.
- DO NOT INTERACT WITH THE COMMENT!
- Delete it from the preview.
- After patch: Comment is deleted from the document, too.

Partly, this moves more code over to the new stuff.
This also allows "r" to work if you have code selected (not just comments). If you "reply" to code, you start a new comment.
You can "R" a comment to quote it. This just starts a new comment normally if you "R" a block of code. This is sort of a power-user version of "quote" since it seems like it probably doesn't really make sense to put it in the UI ever (maybe).
With the new click-to-select, you can click + "R" to reply-with-quote.

Basically:
- When we load content, we try to keep the viewport "stable" on the page, so the page doesn't jump around like crazy.
- If you're near the top or bottom of the page, we try to stick to the top (e.g., reading the summary) or bottom (e.g., writing a comment).
- But, if you followed an anchor to a comment that's close to the bottom of the page, we might stick to the bottom intead of staying with the anchor.
Kind of do a better job by not sticking to the bottom if you have an anchor. This will get things wrong if you follow an anchor, scroll down, start writing a comment, etc. But this whole thing is a pile of guesses anyway.

- Followed an anchor, saw non-sticky stabilization.

- Introduce global "hide everything" states (T8909) so you can completely hide stuff if you want, and this represents more of a halfway state between "nuke it" and "view it".
- Make the actual rendering better, so it says "epriestley: blah blah..." instead of just "..." -- and looks less dumb.

First, Conphernece would try to repaint the UI even if no thread was open. Only repaint when a thread is open.
Second, although we deduplicate JX.Leader messages, we didn't deduplicate actual notification messages. If you browsed the leader window, then it re-elected itelf as a leader and replayed history, it could rebroadcast notifications and other windows could show doubles. Deduplicate notifications to prevent this.
Third, we always replayed the last 60 seconds of history. When you browsed the leader window, whichever window became the new leader (possibly the one you just browsed) could replay messages from before it had opened, leading to duplicate messages. Particularly, after receiving a message and then browsing you could see that message again. Instead, only replay history as far back as when the window first opened.
Test Plan:
- Clicked "Repaint" with a thread open, saw a repaint. Clicked "Repaint" with Conpherence open but no thread, no repaint and no 404 request to `/update/null/`.
