1. Load http://en.wikipedia.org/wiki/Charlie_O%27Donnell#mediaviewer/File:Charlieodonnell_announcement.jpg
2. Hit the full-screen button.

The image transition starts from the wrong position and it cuts off the image.

Could you tell me how the SVG looks like during the transition?

Comment 3 Dirk Schulze 2014-06-16 08:35:00 PDT

Seems like the <svg> is relying on the wrong height calculation code where 100% is equal to 1vh regardless of the containing block. This can just be fixed in the wiki page.

I'm not sure if you're saying this is correct behaviour, or still a bug on our end?

Why does Firefox (whose sizing we match after http://trac.webkit.org/changeset/168350) not exhibit this bug?
