bug#56694: 29.0.50; No mouse-1 menu on mode-line-position in some cases

[miha--- via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

From emacs -q, click on "L5" (mode-line-position) with mouse-1 and turn
on "Display of Column Numbers".

Now click on "(5,0)" (mode-line-position) with mouse-1 and turn off
"Display of Line Numbers".

Notice how the "C0" (mode-line-position) isn't clickable any more.

Best regards.
