Attachment: screenshot 1 - Images don't redraw if animation transition is canceled in the middle.png

>>>   My Info:   Win7_64, Nightly 46, 32bit, ID 20160126030244
STR:
1. Save testcase from comment 1, open .htm file in firefox. I discovered the bug while using Tumblr
2. Click on the page
3.A) As fast as possible {press button that produces 'keyup'} (x4 times)
     I do it like this:   successively press keys "k", "j" in ~0.5 second
3.B) (in more detail) Press "k" key, then, while transition is still not finished, press "j" key

AR: Images don't redraw: you can see several parts of each image in different places (see screenshot)
ER: Images should redraw correctly

This is probably a regression from my refactoring but I won't be available to look at this for some time.
