Load the attached test case, and it spits out the following assertion a few times:

ASSERTION: 3D transform found between fixedpos content and its viewport (should never happen): 'Error', file /Users/kats/zspace/mozilla-git/layout/base/nsLayoutUtils.cpp, line 1769

I wanted to use something like the attached as part of a reftest but since it's spewing assertions it causes the reftest to fail unless I whitelist the assertions which I'd rather not do.
I've definitely encountered this assertion before, but I can't find where at the moment...
I see many of these just by launching B2G-desktop. I don't have to do anything.
This assertion spams continuously to my terminal, if I view http://abcnews.go.com/US/nasa-astronaut-plays-ping-pong-ball-water-space/story?id=36455005 in a debug build.

I can confirm that the attached testcase triggers the assertion for me, as well.

Marking this as blocking bug 946502, which is where this assertion was added.  Maybe mattwoodrow could take a look? (he was reviewer on that bug and has been working with other 3d transform stuff recently)
