Linked demo doesn't work, the 2 videos are displayed on top left corner of the canvas. They should be rendered inside the 2 SVG resizeable rectangles.
Changed component to SVG, so it shows up in my all-svg-bugs search.
Is this a duplicate of https://bugs.webkit.org/show_bug.cgi?id=23113 ?
It looks very similar yes, but I'm not really a SVG expert, can't confirm for sure
For what it's worth, I can confirm that this is still an issue in r103794.
I cooked up a test case here:
(Warning: video auto-plays with sound)
View in Firefox (I tested 8.0.1) for the correct display. In WebKit, the video is not transparent, is not scaled, isn't positioned correctly, and appears on top of the red text area, instead of underneath.
Tested in: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_2) AppleWebKit/535.15+ (KHTML, like Gecko) Version/5.1.2 Safari/534.52.7
I'd be happy to help build additional test cases, if requested. Patches, however, are a bit outside of my skill level. :)
Hoping this is helpful,
