I suspect the culprit is Bug 1653317 - Use TabDialogBox for tab modal print UI

This seems like it should be partially fixed by bug 1661361 (which landed on mozilla-central about three hours ago)…
And if not, we're doing more investigation in bug 1661157, so I think we should dupe this to that one.

I can confirm that the issue is not present on macOS 10.14 with the latest 81.0b5. However I am still able to reproduce it on macOS 10.15 on the same device (new profiles)

Bug 1661361 hasn't been uplifted yet, but it's interesting that you see it on 10.15 and not 10.14…
Please leave that (and any further investigation you do) as a comment on bug 1661157, since it seems like it could be helpful, if not in diagnosing the problem, then in figuring out what platforms to concentrate on!
