FWIW, I just re-tested as promised. Unfortunately, I got a new work machine in the last six weeks (and no longer have the old one), so I can't test on the same hardware. I was previously able to reproduce it on my *home* machine, though, so I've re-tested there as well. Here's what I found:
1. No issues with current versions of Chrome (Version 80.0.3987.149), Chrome Beta (Version 81.0.4044.83), Chrome Dev (Version 83.0.4093.3), and Chrome Canary (Version 83.0.4097.0). on either machine.
-- Most of these are clean installs, though, that don't get much usage, so they mostly don't have any extensions installed, etc.
2. Microsoft Edge Canary (83) still exhibits the problem on my *home* machine, but not on my work machine. (Beta & Stable channels worked fine in both places.)
-- So the problem is obviously somewhat machine dependent.
-- I tried disabling all the extensions I had installed, but it didn't help. (Mostly the same extensions installed at home & work, though, so that was a long-shot.)
I'm not sure that helps anyone... but there it is.
