Summary Web Inspector: Cursor and scroll view jumps around when modifying styles

Created attachment 239362 [details] Shows position of dock and window of when bug can be replicated Seen on OS X Yosemite GM (14A379a), Safari 8 (10600.1.25). To replicate, load the web inspector for a page and inspect an element. Ensure the web inspector is docked. - When enabling / disabling a style, scroll area jumps around - When adding or modifying a style, as you start typing sometimes characters are "skipped". E.g. typing "margin-top" will sometimes result in "marin-top" as characters are dropped - Cursor also sometimes jumps to start / end of line sporadically when editing - And scroll view of dock will scroll up and down too Could be related to the autocomplete feature, as I notice if I type slowly and use the auto complete, I can sometimes prevent the cursor jumps / skips See attachment which shows position of dock and window of when bug can be replicated.

Comment on attachment 241190 [details] Patch r=me. Never thought I'd review a patch that used the word "blinky" in it.

I’m still seeing this in both Safari 8.0.2 (10600.2.5) and WebKit r178028. Screen recording of the issue, taken with WebKit r178028: http://roguewhaler.net/files/web-inspector-jumping.mov Should I file a new bug for this?
