This can happen in a combo box if the dropdown is shown by a mouse click +
release followed by the mouse being moved into the dropped listbox (when
the listbox has nothing selected). In this case, the first item (with the
index zero) would not be selected the first time the mouse moves over it.

This can be easily tested with winecfg. Launch winecfg, go to `Libraries`
tab, click on the combobox arrow dropdown for `New override for library`
to open the listbox, then hover the mouse over the first entry (acledit).
Notice that it does not get highlighted, which is the issue. If you move
the mouse to the second entry (aclui) and then back to (acledit), it works.
