If you edit an existing header or post in Firefox and Chromium in wiki text mode,
* The textarea starts out two lines tall regardless of how many lines of text it contains.
* The textarea has no scrollbar regardless of how many lines of text it contains.
* The textarea has no resize grabber handle.
The moment you press a key in the textarea (even an arrow key), it autosizes to its contents, which is good but
* It autosizes regardless of the window size or scroll position.
* There seems no limit to how big the textarea gets.
* After I Cancel or Submit changes of a 130-line textarea, the original post (probably much less tall) doesn't scroll into view, I'm left at some random point in the document.
** (And because there are dozens of empty comment areas on the board with my name, I can't search on my username to find my just-edited post, but that's a different issue.)

I think most of these are side-effects of the fix for bug 56131 "reply and edit text boxes do not expand." There are many jquery.*resize* libraries addressing this, Benny comments "we used jquery.elastic for Moodbar." (FWIW, ooui doesn't seem to support this.)

While I'm here, I also note that clicking the pencil icon to edit the header or a post does not set the input focus to the textarea. It should, and that might fix some issues.
