bug#53677: 29.0.50; Incorrect cursor-in-non-selected-windows on --with-pgtk

[Protesilaos Stavrou]

Dear maintainers,

In my current build of Emacs the cursor in non-selected windows does not
use the correct style of a hollow box, as described in the doc string of
cursor-in-non-selected-windows.

Instead, a line is drawn at the top of the box where the cursor was.
See attached screenshot: the cursor in the unselected window is at the
end of the statement "Its value is t".

To reproduce on emacs -Q just split the window.

My build information is further below.

All the best,
Protesilaos
