This bug was originally reported on webcompat.com anonymously: https://webcompat.com/issues/3297

STR:
1) Navigate to: https://jsfiddle.net/h7gpxc4w/
2) Move mouse around

Expected Behavior:
Outline property width on row is consistent even with non attached mouse movement

Actual Behavior:
On Firefox, if I move the mouse then the outline width changes in animation. In Chrome it is consistent.

I am able to reproduce this in Firefox 49 and 52 on OSX and Windows 10.

Looks like our outline size depends on the content, and transform happens in compositor thread so the outline size is not updated properly during animation?

I guess we can probably change the outline impl to not depending on the content, so that its size would be consistent across repaint. If this isn't breaking any real site, I don't think it has a high priority, though.
Given there are more discussion in bug 1305976, duplicate this one into that.
