James Teh 0ec1287aed Bug 2040856 part 2: Don't include display: contents nodes in the accessibility tree if an ancestor is inert or visibility: hidden. r=eeejay ...

We already excluded most nodes in a visibility: hidden or inert subtree.
However, we previously checked this only on the frame of the node itself, and since display: contents nodes don't have a frame, they weren't excluded.
We now check ancestor frames of display: contents nodes for visibility: hidden and inert, just as we already did for content-visibility: hidden.
