editing/unsupported-content/table-delete-003 is failing on the buildbot.
<rdar://problem/5237074>
This regression is a result of allowing whitespace-only text nodes inside table elements. The table is not removed during deletion because its entire contents are not selected: there is a whitespace text node following the last table row which is not selected. I don't know enough about editing to be able to tell if the selection should include that stray text node or if the deletion code should check for this case and handle it.
I'm going to look into this.
