See the testcase at https://bugzilla.mozilla.org/attachment.cgi?id=523831 on which the yellow square should be on top of the red one.

In particular, the 2d transforms specification says that transformed elements act like position:relative for stacking purposes, so z-index should apply to them.

It's not obvious to me that z-index should apply. They act as positioning containers, but that doesn't necessarily mean that z-index applies.

This is worth a post on www-style.
Comment 3 Simon Fraser (smfr) 2011-07-07 07:59:09 PDT 
Consensus was to not have z-index apply.
