Hello,

Up to emacs-27.2 I was using this code:

    (with-current-buffer helm-buffer
      (let ((frame (selected-frame)))
        [...]))

selected-frame was returning the frame where helm-buffer was displayed.
In emacs-28, it have the same behavior when helm starts from a normal
buffer, but if I call helm from a minibuffer e.g. from M-:
selected-frame is returning the wrong frame whereas in emacs-27, the
frame handling helm-buffer is returned.
I expect here having the same behavior in emacs-27 and emacs-28.

Does something have changed in selected-frame?

Thanks.
