1185376 - On mouseover flipped image with backface shows flipped frontface on mouseout

Status: NEW

(Core :: Web Painting, defect)

Description

[Elbart]

Attachment: backface_flip.mp4

Open URL and hover over any of the portraits.
The images will flip horizontally, and show some text on the backside.

When moving the mouse out of the image-area, the text immediately disappears and the flipped front-side is shown for a bit during the transition.

Before the regression, this was not the case.

The lack of hq-scaling of the portraits is probably because of bug 803703/bug 1182929/bug 1183378.

The problem is compatibility between themify script(http://themify.me/) and Firefox.
The themify script seems widely used.

Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
