If I do:

C-h k and press mouse-1

It shows 2 events:

There were several key-sequences:

  <down-mouse-1> at that spot runs the command mouse-drag-region
  <mouse-1> at that spot runs the command mouse-set-point


But:

C-h k and press Control + mouse1

I only get:

C-<down-mouse-1> at that spot runs the command mouse-buffer-menu
(found in global-map), which is an interactive native compiled Lisp
function in ‘mouse.el’.

It is bound to C-<down-mouse-1>.

(mouse-buffer-menu EVENT)

There is not such event like C-<mouse-1>

So this is actually the issue.

Maybe.

There are mouse-X down-mouse-X S-mouse-X S-drag-mouse-X and
C-down-mouse-X. But not any C-mouse-X

So maybe this explains what I described above.
