Sorry, I meant "revert 5318b103f" here.  But it does not make sense for
0d6f84aab, since it's not there!  It would be good to test it though,
since it comes from a 'core-updates' merge around the same time.

If 0d6f84aab works, good candidates to try next is reverting 5318b103f
on top of 0d6f84aab, 9a1f92a6e, and faccae1c3.

Hope this helps, and thanks for your patience here!
