Hi,
Thank you for looking into this.

What is `gnus-mouse-2'? I do not seem to have a variable or function of
that name.
I tried C-h k mouse-1 after the line end and also inside the group
string.
For Enacs 25 I get this for after the line end:
<down-mouse-1> at that spot runs the command mouse-drag-region (found
in global-map), [...]
----------------- up-event ----------------
<mouse-1> at that spot runs the command mouse-set-point (found in
global-map), [...]
Inside the groups string I get:
<down-mouse-1> (translated from <mouse-1>) at that spot runs the
command mouse-drag-region (found in global-map), [...]
----------------- up-event ----------------
<mouse-2> at that spot runs the command gnus-mouse-pick-topic (found
in gnus-topic-mode-map), [...]
While for Emacs 26 I get this for both:
<down-mouse-1> at that spot runs the command mouse-drag-region (found
in global-map), [...]
----------------- up-event (short click) ----------------
<mouse-2> at that spot is remapped to <mouse-2>, which runs the
command gnus-mouse-pick-topic (found in gnus-topic-mode-map), [...]
----------------- up-event (long click) ----------------
Pressing <mouse-1> at that spot for longer than 450 milli-seconds
runs the command mouse-set-point (found in global-map), [...]
IOW, after the line end there is an additional handler for mouse-2 in
Emacs 26, that was not there in Emacs 25.

`mouse-1-click-in-non-selected-windows' would change this particular
behaviour, but it is not what I want either :-(. I prefer to have a
button or link activate when I click on it, without having to care if
the frame was active or not. It's just that in the case of the Gnus
group buffer, the whole client space is active, even where it used to be
not (and IMO should not be).

That works for me, thank you. It's `gnus-mouse-pick-topic' for me,
because I have topics activated, sorry for not mentioning that before.
(If I disable topics, the same problem occurs, so that by itself seems
not to be the cause of this.)
