* bug#18249: 24.3; expected a button click, text pasted into button label instead

Hello,

  I found some odd behaviour while clicking with <mouse-2>
over a button. I can't say if it's exactly a bug, but I believe
it's unexpected and unwanted behaviour for the user. Here's
a recipe to replicate it.

1) start emacs -Q
2) clear buffer with C-x h C-w
3) type or paste the following five lines of text (line 3 is
   empty on purpose):

;---------- line1: start
(insert-button "[ciao]" 'action (lambda (x) (message "ciao!"))) ; line 2

; line 4: pastethis
; --------- line 5: end

4) put the text cursor at line 3, type C-x C-e so that 
   the "[ciao]" button will be created in line 3
5) select the word "pastethis" with the mouse, by dragging with
   mouse-1 button from first to last letter of the word
6a) put the mouse cursor over the [ciao] button and click there with
    mouse-2 (center button). Result: you should see that the message
    "ciao!" appears at the bottom line; this is correct and expected
    behaviour
6b) move the mouse cursor over the letter "i" of the text "line 4:",
    click mouse-2 and hold it pressed; continue dragging and move the
    mouse cursor over the [ciao] button, then release mouse-2.
    Result: you should see that the word "pastethis" has been pasted
    into the button label, so that it looks similar to
    [ciapastethiso]; this is unexpected behaviour.

  May I please ask if the result 6b) is reproducible for you too.

  I believe 6b) is odd/buggy because typically the user wants
to do action 6a) but accidentally drags the mouse by a few pixel,
thus actually performing action 6b). Please let me know if this
opinion seems wrong/flawed to you.

  If the above makes sense for you too, then a possible correction
could be: if a <drag-mouse-2> event ends on a pushable button,
then Emacs should always perform the button action, not a text
paste like it does now.

  Thanks for your attention and patience in reading this,
kindest regards.

  Andrea

(I'm going through old bug reports that unfortunately have not received
any responses yet.)

I tried this in Emacs 27, and I was unable to reproduce the bug.
Holding down mouse-2 and moving the mouse around just moves text around,
and releasing it doesn't do anything special on the button inserted.

Are you still seeing this bug?

  and thanks for your feedback. I confirm I can still reproduce the
issue on these binaries:

https://alpha.gnu.org/gnu/emacs/pretest/windows/emacs-27/emacs-27.0.50-snapshot-2019-06-08-x86_64.zip

M-x version RET
  
GNU Emacs 27.0.50 (build 1, x86_64-w64-mingw32) of 2019-06-09

  Tentative explanation: if you tested on a Linux workstation, then it
could be a Windows-only problem. Or maybe my step 6b is ambiguous or
hard to follow. Let me retry:

  Maybe describing 6b more naively may help, let me try:

  6b) press mouse-2 outside [ciao], drag mouse inside [ciao], release mouse-2. 
      Instead of clicking the button, it pastes text inside the button.

Cheers!

Ah, I guess that sounds likely.

Yup; I'm not able to reproduce this in GNU/Linux, so somebody with
Windows should try to chase down why this happens there.

I am able to reproduce this at will in GNU/Linux, though.

Details:
x86_64-pc-linux-gnu
Ubuntu 18.04.5 LTS

I can reproduce this with current master on Debian stable/bookworm.
