[PATCH resend 1/2] comctl32/combo: Don't redraw the Combo Box when dropped down if it has an editbox.
Some applications subclass the combo box and handle WM_ERASEBKGND themselves, without using WS_CLIPCHILDREN. This causes them to erase over the editbox child. There's no reason to redraw it in this case since the editbox is supposed to cover it, anyway.
