Bug 1913848 [wpt PR 47678] - Update dir=auto traversal tests to not a…

…pply element-only rules to ancestors, a=testonly

Automatic update from web-platform-tests
Update dir=auto traversal tests to not apply element-only rules to ancestors

This fixes web platform tests to match half of the spec update in
whatwg/html#10488 and
whatwg/html#10561 .  Prior to this change (in
spec and Gecko, although not in the Chromium code) the special rules for
dir=auto traversals that were intended to apply only to dir=auto on an
element and not to dir=auto on its ancestors (relating to
auto-directionality form-associated elements and to slots) were being
applied in one ancestor case, where the special element was an assigned
node of a slot.  This makes the test changes corresponding to the fix to
the HTML spec.
