bug#49248: 28.0.50; read-from-minibuffer returns a window-live-p error when its original window is deleted

[Thierry Volpiatto]

Hello, I have a bug report
https://github.com/emacs-helm/helm/issues/2424
where it seems a minibuffer not belong anymore to its window when this
one is deleted.
Here is what's happening:
I have a function that change the place of the window where originally
read-from-minibuffer was called, the window goes right, left, up and
down at each call of this function, but once we press RET to exit the
read-from-minibuffer an error is raised:

Wrong type argument: window-live-p, #<window 38>
(See backtrace in the link to helm issue mentionned above)

The error seems to come from read-from-minibuffer.

This always worked since emacs-24 to emacs-27.2.

Here is the function:

https://github.com/emacs-helm/helm/blob/master/helm.el#L6596

I wonder if this is a bug or an incompatible change in emacs-28, if so
what are the new directives in such case.

Thanks.
