Description Michael Catanzaro 2017-09-12 13:04:29 PDT

After enabling G_DEBUG=fatal-criticals for our layout tests, the following tests:

accessibility/aria-tables.html
accessibility/table-sections.html

Are now crashing with the following error:

STDERR: atk_object_get_attributes: assertion 'ATK_IS_OBJECT (accessible)' failed

Updating expectations accordingly. Here's a crappy backtrace from accessibility/aria-tables.html:

Pretty sure this is a duplicate of 179837. Marking as such since the tests are now passing "unexpectedly" for me with my proposed fix for that bug.
