Sure, I'll do that. Thank you.
But are we not going to consider a cleaner/correct solution such as the
one proposed here:

Well, honestly I don't mean to be stubborn, but somehow, knowing that
there are issues with my patch doesn't make me feel very comfortable
going with it, especially when there is another approach, which I
believe can fix the issue properly, without undesirable side-effects.

I agree that the issues are mostly some corner cases, so if you want a
quick fix for now, I guess we can go with this patch and then later on
follow-up with a proper solution to this whole problem.
