981350 - hover animations of the two halves of the "Bookmark this page"/"Show your bookmarks" toolbar button are different

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

STR:

1. Move the pointer to hover over the right half of the "Bookmark this page"/"Show your bookmarks" toolbar button.
2. Notice that the hover animations on the right button seem to run ever so slightly more quickly than the ones on the left.

Maybe the background of the button is animated at a different rate than the borders?  Or maybe they're the same but the animation of the background too gives the appearance of these having different animation durations.

Same for the hover-away animations.

I suspect it's because the left part's animation is dependent on an attribute which is set from JS. The obvious fix would be making the right part also use an attribute, which seems weird. :-\

Irrelevant after Photon?
