Local display function fails with HDMI in moOde 7.0.1

I was reading the release notes for the 2021-01-11 release of RaspiOS and noticed this:

 * Chromium version 86.0.4240.197 included

It turns out this same version is now in the testing repo for the release of RaspiOS on which moOde 7.0.1 is built.

When I installed this version of Chromium to a moOde 7.0.1 player (on an RPi3B+ with local HDMI display) and reran my monitoring test overnight I did not see the failure mode we've discussed previously.

I'm curious to know if you experience the same result.

Code:

# first, remove old version
sudo apt-get remove chromium-browser

# then install the testing version
sudo apt-get install -y -t testing chromium-browser

# reboot if you're as superstitious as I am.

There's no need to make any other changes to moOde (notably, not to /home/pi/.xinitrc)
