Re: [fxtf-drafts] filter should be defined to establish a containing block for fixed and absolutely positioned elements

I think the idea is that a `filter` on the root element (and *maybe* also the `body`) would:
* not change any containing blocks
* set the filter on the canvas rather than the root element's box (or `body`'s box, if applied to `body` as well)

This would apply that `position: fixed` elements would be filtered by a filter on the root, but they'd also still be fixed rather than behaving like absolute as other `position: fixed` elements with an ancestor with `filter` would.

It's probably worth checking with some others with the discussion that they agree that was the intent.
