Actual results: The element with that style is not rendered. Expected results: The element should be rendered, preserving its 3D properties. The equivalent -webkit-* styles are applied as well, so a webkit browser can be used for comparison (works with Chrome and Safari/iOS).

This fixes the image being invisible, but doesn't cause the perspective to be applied. As far as I can tell the perspective frame (the <body> element) isn't a parent of the transformed frame (the <img> element), so perspective shouldn't be applied. I'll construct a reduced test case for this and ask for clarification on the spec.
Attachment #574432 - Flags: review?(roc)
The <body> is not a parent because the direct parent of the <img> is float:right? Or because the perspective has to be set on a direct parent?
The spec says http://dev.w3.org/csswg/css3-3d-transforms/#perspective-property The ‘perspective’ property applies the same transform as the perspective(<length>) transform function, except that it applies only to the positioned or transformed children of the element, not to the transform on the element itself. That property is not inherited. The "img" is not a child of the <body>. So the body's 'perspective' does not affect it. If Webkit behaves differently, maybe we should change the spec to match Webkit. That would need to be discussed on www-style.
(Maybe perspective inherits in Webkit?)

Definitely looks like webkit is treating this as an inherit property, or they are interpreting 'children' as 'descendents'. I'll take a look at the WebKit source code and post to www-style.
