[-- Attachment #1.1: Type: text/plain, Size: 5385 bytes --]

tty-child-frames does not seem to play well with multiple clients. When we
run server-start and allow emacs to have multiple clients (e.g. an initial
"emacs -nw" and an
"emacsclient -nw"), using a function that utilizes tty-child-frame (such as
M-x when vertico-posframe is loaded) in one frame leads the other client to
be locked up.

Steps to reproduce:

mkdir ~/emacs-test
Copy the attached init.el into ~/emacs-test/
emacs -nw --init-directory=~/emacs-test  (the first time will result in
packages being installed by elpaca)
(in another terminal) emacsclient -nw
Do something to invoke the child frame pop up (e.g. C-x b and select a
buffer)
Switch back to the original emacs
Do something to invoke the child frame pop up (e.g. C-x b and select a
buffer)
Swap to the other terminal, and note that at some point one client will
stop responding
to user input. (It may take a couple of tries, perhaps with other regular
commands interspersed).
When one client is locked, swap back to the other terminal and exit the
client - the original
client will now accept user input.

When a client is locked it *does* accept some input (e.g. C-x C-c will exit
the client)

It's possible this is vertico-posframe related, as I can't trigger similar
behaviour using transient-posframe.
