bug#43793: 27.1; Clicking on grep-mode find-abbreviate ellipsis yields user error

Hi,

Clicking on the find-abbreviate ellipsis in a grep-mode buffer
while focus is on another emacs window invokes the
grep-find-toggle-abbreviation on the buffer in the focused window
instead of in the clicked window.

The common manifestation of this problem would be a user error because the
abbreviated-command property can not be found. More interesting results
can be achieved if the focused window contains another grep-mode buffer
in which case the ellipsis will be expanded in the focused window
instead of the clicked.

Attaching a patch the invokes mouse-select-window before toggling the
abbreviation.

Best regards,
David Landell

Subject: [PATCH] Grep: Ensure window is selected when clicking on
 find-abbreviate ellipsis

Without this fix, clicking on the abbreviate ellipsis when focus is on
another window invokes grep-find-toggle-abbreviation in the focused
window instead of the clicked one.

* lisp/progmodes/grep.el (grep-find-abbreviate-properties):
Invoke mouse-select-window before toggling abbrevation.

Hmm, this didn't reproduce for me with emacs -Q.
Probably something in my config. Please close this one.
