Re: Overflow-clipping of filters with fixed-pos/abs-pos descendants

We need a resolution here sooner rather than later, please. It'd be great
if someone from the IE or Chrome teams could contribute to the discussion...

A bug related to this issue just cropped up in the wild:
https://bugzilla.mozilla.org/show_bug.cgi?id=1125767,
http://jsfiddle.net/lastw/auv3x2y9/. In that bug, a filtered element E has
an abs-pos descendant D for which E is not a containing block ancestor. In
Gecko, D is cropped to E's bounds. In Chrome, D is not filtered. I think
both of those behaviors seem wrong.
