[Bug 43465] Unit Test: ComboBox Dropdown does not work if Style is set and no scrollbar required

https://bugs.winehq.org/show_bug.cgi?id=43465

--- Comment #6 from Fabian Maurer  ---
This is not a working solution yet, I just try to narrow down the error.

I'm not too experienced with the wine code, I guess it would be helpful to know
what the program is doing, but this looks like Delphi classes where the source
is not available.

Since I don't have Delphi, could you possible provide a sample with multiple
comboboxes with different numbers of items? I still don't understand how the
problem changes if a scrollbar is needed. Like, when there are enough items in
the combobox for the scrollbar to display.
