bug#51742: 29.0.50; user-error: Cannot invoke transient emoji--command-Emoji while minibuffer is active

[Jean Louis]

I am editing entries in minibuffer and then if I wish to add emoji,
there is this problem:

user-error: Cannot invoke transient emoji--command-Emoji while
minibuffer is active

This brings me that I need to write emoji somewhere, kill and yank it
into minibuffer, instead of directly inserting it in the minibuffer.

This is because of:

(defun transient-setup (&optional name layout edit &rest params)

[...]

  (when (> (minibuffer-depth) 0)
    (user-error "Cannot invoke transient %s while minibuffer is active" name))

Jonas, is there any reason for this check?  Things seem to work just
fine if I remove it.  (Or perhaps the check should be removed if
enable-recursive-minibuffers is non-nil?)

In most cases it just works.  But when it does not work then it doesn't
just fail gracefully but can result in emacs having to be killed from
the outside because of inconsistent state of transient maps and hooks.
At least that was the case in the past.  I have some changes sitting in
the next branch that should fix that.

I actually was working on making sure that there are no remaining
edge-cases when a new wave of feature requests and contributions started
to arrive and I had to shift my focus.  But I plan to resume work on
this very soon.  For testing purposes you can use the next branch and
remove this check, but it is not ready for general use just yet.

OK; we'll just leave this report open until these changes have been
merged, then.

Looks like this has been merged, because I can no longer reproduce the
test case from Jean.  So I'm closing this bug report now.
