These changes don't seem to actually change anything in terms of functionality - is this purely a performance fix?

ok, so the difference here is that if the starting node is the highest node in the shadow DOM, then the old code did not find a matching host node - whereas this code does?

The problem is that if the child is a directly on the shadow root, it would start looking from the host (outside the shadow), even though the matches array still only contained elements inside the shadow tree.
Followup thought, should this use element.matches() instead of doing querySelectAll() and see if the element is included? I imagine that'd be faster.

shouldn't this attach to the div with role="list"?
Should help resolve #422.
