1202033 - Use the containing block for determining preserve-3d parents for transformed elements.

Status: NEW

(Core :: Layout, defect)

Description

[Matt Woodrow (:mattwoodrow)]

+++ This bug was initially created as a clone of Bug #1202029 +++

The latest versions of the transforms spec [1] say that we need to check the containing block element of the transformed element when looking for a preserve-3d parent , rather than the parent element.

I don't think this should break web compat, since it seems very rare that the author would have preserve-3d on an ancestor that isn't the parent and really didn't want the preserve-3d respected.
