While Po's patch fixes the read-args focus bug, I now have a new bug. It
happens irregularly and I can't say for sure yet that it's caused by Po's
patch. I don't know what triggers it but it seems I need to have at least
two edit frames open.

What happens first is the mouse pointer disappears, but I can still edit.
After a while emacs hangs and ignores all input. A bit later it won't even
redisplay frames on X exposure.

Here is the stack when it hangs:

Note this is Po's patch on top of stock 29.1. If I get ambitious I'll try
building from master.

I would not normally report a bug with such sketchy information but I
thought you should know. If I figure out anything more I will make a proper
bug report.
