No, it seems to be frozen for all time (at least until I got bored
waiting, which was probably 20 minutes).  Even if I reboot the machine,
the current screen state stays until the system powers off.

I've actually got a VGA display plugged in over a USB-C to VGA
converter and that's working fine in mirrored mode even as the panel is
completely frozen.
