Throbbers get out of sync when dragging tabs
59 bytes, text/x-review-board-request
If you drag a tab while it has a loading throbber in it, the throbber loses sync with other throbbers in the same window. STR: - Create a bookmark folder with a fairly large number of tabs (e.g. 20 or so) - From that folder, perform an "Open All in Tabs" - While the pages are still loading, drag one tab to any location other than its starting one - Observe that throbber on the dragged tab is no longer in sync with the other tabs' throbbers (I discovered this in a less contrived but harder-to-reproduce situation involving only two tabs -- so it does arise even without a large number of tabs loading at the same time)

Comment on attachment 8929061 [details] Bug 1408152 - Sync the throbber animations again after the tab has finished moving. I'd be curious to know what re-starts the animation. Perhaps something clobbers the animation-name property? We could set a breakpoint in nsAnimationManager.cpp to find out or even just listen for 'animationcancel' events (assuming the animation is actually being re-created). In any case, _syncThrobberAnimations should be safe to call repeatedly so this seems fine to me.

That seems cleaner than this... Otherwise this looks OK to me given bbirtles is happy? Up to you if you want to re-request review and/or do more digging.

I pulled out the function and put it on tabbrowser with a `tab` argument. I'll land this now since the refactoring is pretty straightforward.
