local html example of the bug
Overview: More detailed restatement of summary.
When hovering over an element that triggers the hover function and sets a transform in motion, it blocks the -webkit-mask and thus it disappears.
triggering the bug:
or look at the attachment
2) hover over the div element
Actual Result: mask disappears while transform is in motion. It appears again when the animation is done ( let your cursor rest for about 2 seconds on the div )
Expected Results: The mask should hide the overflowing content, even when the transform is in motion.
Build Date & Platform: Webkit-svn-r68887 build 01-10-2010 on Windows Vista
Build 2006-08-10 on Mac OS 10.4.3
Additional Builds and Platforms: Whether or not the bug takes place on other platforms (or browsers, if applicable).
Additional Builds and Platforms: As far as i know, it occurs on every os and platform (send the bug to paul-irish, he asked me to file it here)
Additional Information: Tried to solve the bug with an overlaying div element, with again a mask. Gave the same result. Example http://cssdesk.com/j3JcH
Can you make a very simple testcase with just one element? It's not clear to me from this (cool!) testcase what the issue is.

Zip file containing test of bug.
Notice that once scaling is applied to the image, the mask no longer works.
Your testcase works perfectly for me. What OS and browser are you testing with?
Works for me as well.
