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.

Iām 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?
Yes, please do.
