Comment (by kjak):

 I have added a changes file to this PR.

 But let me know if I should close this PR (which is for master) and open
 up a new one for maint-0.3.5 instead (similar to what I did for #28995),
 or if it's OK to leave it this time.  (Recall from above that this failure
 occurs on 0.3.5 but not on 0.3.4.)
