How is the change listed at #1 looking in canary?

The change is expected to fix a bug we very rarely see. Canary build seems fine and I wasn't able to reproduce the bug but it's possible it had no effect too. Given that the change should have no undesirable side effects and at best fix a bug and only impacts a feature that is behind a Finch flag, I think it's safe to merge.

Approving merge to M69 branch 3497 based on comment #5. Please merge now. Thank you.
