I think it was this one: https://chromium-review.googlesource.com/c/chromium/src/+/1145315

Not from me, but I know how to fix it, so I'm working on it.

tangltom@: Would it be safe to merge the CL from C#7 to M-69 branch as well?

Yes, this is a tiny change and should be safe to merge back to M69.

This bug requires manual review: M69 has already been promoted to the beta branch, so this requires manual review
Please contact the milestone owner if you have questions.
