bug#59785: 30.0.50; mouse-2 > (wrong-type-argument listp #<frame *Calendar* 0x...>)

[Michael Heerdegen]

Hello,

I get errors when I click with mouse-2 on a date in the *Calendar* in a
frame that has no input focus.

Recipe from emacs -Q in X:

Enable debug-on-error if you want to get a backtrace.

C-x 5 2 (Open a second frame.)

Select it and M-x calendar RET

Select the first frame.

C-h k  and click with mouse-2 on a date in the calendar in the other
frame.

I get:

C-h k seems only a random command suffering from this issue.  I
discovered the problem while choosing a date from the calendar for
org-capture.  mouse-2 gives these errors while mouse-1 seems to work.

Oh, it seems the Calendar part is not even necessary, the only important
thing seems to be that you click with mouse-2 into a frame that doesn't
have focus.  That already gives the error.

TIA,

Michael.
