I realized that there had already been the same fix on staging.  I had
to spend some time to manually resolve "conflicts" (which were not
immediately apparent due to code having changed place on core-updates).
The conflict cherry-picked from core-updates which ended up fixing this
was 30759c4aadf279e470e8d7f94de332a31c1b9f42.

I rebased the commits that had been pushed to master on that and a few
related others, and pushed as d5c9cc6d9d979bfca5f035429bcf510a0a2285a3,
which contains extra comments.

Thank you!

Maxim
