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

@isiahmeadows Filters create a containing block for descendants now. This means, the behavior of Firefox is following the spec with the edits from . The `filter` behaves like `transform` now.

I should probably modify this sentence as clarification:
> Any value other than `none` for the `filter` property causes the element to become a containing block, and the object acts as a containing block for fixed positioned descendants.

Just for completeness: `filter` also create a stacking context. The spec states that a couple paragraphs later.
