Created attachment 8699948 [details] pulse.html STR: - open the attached HTML test case - open the inspector, select the div and switch to the animation inspector tab - you should see 2 animations, that's because the div has 2 css keyframe animations defined - click anywhere in the time graduation header in order to move the scrubber to that position => Expected: the scrubber moves there and the animation pauses => Actual: the scrubber disappears, the animation pauses correctly though Looks like the whole timeline is refreshed when this happens. Now, try removing one of the animations (you can do this in the rule-view for instance). Switching back to the animation tab does the right thing, only one animation is displayed now, and clicking/dragging the scrubber does work.
I can't reproduce this bug in Nightly. The animation pauses and I still see the scrubber. Can you tell me if you can reproduce ?
Can't reproduce anymore either. Closing as WFM.
