short video depicting the problem

In the campaign editor for HoMM4 I can't use the left mouse button to select
from the available portraits because only 2 of images can be selected: the
first one and the last one.That is when clicking on the up and down arrows with
the mouse button, next to the hero's portrait.
However if I use the mouse wheel to cycle through the available images then any
of the available portraits can be selected.

The last Wine version where the mouse button still worked: Wine-7.5.
This is the commit where the problem first occured:
commit d42888f07c6e3e491c99bb5c8b62b568264e990c
user32: Use NtUserMessageCall for SendMessageA implementation.

Plain terminal output doesn't show anything related.
Demo version is not available. I tested with the GOG.com version of the game.

Still present in Wine-10.0-rc1.
