[Bug 43643] Combobox not longer has dropdown

https://bugs.winehq.org/show_bug.cgi?id=43643

--- Comment #2 from Fabian Maurer  ---
Can confirm this doesn't work anymore since my patch, I'll look into it.

It never seemed to have worked properly, but the wrong behavior was hiding this
issue.
For example the "Scale view by" or the font-dropdown, they do still work, but
are way to small. Even when reverting the patch their size is wrong.

The application seems to set the size in a way I don't yet understand, and that
doesn't work properly under wine. I couldn't reproduce it yet when creating
comboboxes in a test application, so if you have more information I'm glad to
hear it.
