Hmmm, the repro scenario I gave doesn't involve either emacs client being still in the minibuffer AFAIK - the "working" client is just in a regular buffer (e.g. having been chosen via C-x b and selected), and the "hung" client is, well, hung.

To elaborate my steps:

emacs -nw --init-directory=~/emacs-test (the first time will result in packages being installed by elpaca)
(in another terminal) emacsclient -nw
Then invoke the child frame pop up: (e.g. C-x b and C-n to select *Messages* and RET). Now we're no longer in a minibuffer.
Switch back to the original emacs

Swap to the other terminal, and note that the client is "hung".
