Load this demo:

Click on the Firefox logo before the page is completely loaded: transitions start but don't finish.

Same behavior if I zoom/unzoom during the transitions.

Was this a recent regression or has it been a problem for a while?

I don't know. Just run into the same problem in another demo.
How can I help?

I started to try to hack restyling the root frame into the restyle tracker (which would allow simplifying everything here between the SetProcessingRestyles() calls to the posting of an appropriate restyle event for the root frame), but it seemed like too much work.

I still need to write an automated test.

(Oops, I guess the commit message for the first patch wasn't really right anymore, though.)
