I have added that fix to 4.14 now, and will go push out a -rc3 for both
4.19.y and 4.14.y to try to sync up on this and figure it out.

Jon, if you could retest 4.14.y, that would be great, to see if it has
the same issue that 4.19.y has. And if so, that means I should probably
just drop both patches from both trees, right?
