I am actually not convinced this fix is needed for 4.14 (or earlier). I couldn't reproduce this bug.
I think we also need Pasha Tatashin's time series (38669ba205d1 and friends) for the problem to show up.
It happens after f94c8d1169, and it was really easy to reproduce for me (or not to) during bisecting.

Hmm.. I ran 4.14.91 and see no problems.
