Given when this started (on 11/5/20), I wonder if it is related to https://trac.webkit.org/changeset/269434/webkit

I haven't tried reproducing this locally, just noticed it appearing frequently while looking for something else on the dashboard.

Yep, we probably need something similar to r270137 for the same reason.
