…ing contexts In order to properly support `mix-blend-mode` stacking contexts that are parents of child stacking contexts with `mix-blend-mode` in their style need to be marked with the is `IS_BLEND_CONTAINER` StackingContextFlag. In addition to correcting the display of `mix-blend-mode` content, this also work around an issue where `mix-blend-mode` was causing a panic when combined with a particular transform. This also works around a variety of WebRender bugs that happen when `mix-blend-mode` is used near the root stacking context. Signed-off-by: Martin Robinson <mrobinson@abandonedwig.info>
