Uncaught undefined after 2v20?

I'm not sure if I should log this or if it's just me (or if it's already logged and I'm just not seeing it):

After firmware version 2v20, if you make a settings change like switching from light to dark theme and back out, when BangleJS 2 reloads, an "Uncaught undefined" exception shows up at the end of the log.

I went backward in firmware versions until it went away and found:
2v19 - After reboot, no errors in the log
2v20 through 2v21.31 - After reboot an Uncaught undefined shows in the log

I uninstalled all apps except "Simplest Clock", "Settings", and "Bootloader" while testing. Wasn't sure how to debug it further, since it seems to be happening during an event or something after boot.
