DropDownStyle matters because it is not showing any dropdown listbox, and it
ignores DropDownHeight, so the height needs to be handled in a different way
;-)

But the case with the combobox using ComboBoxStyle.Simple seems to be actually
a .net bug, since that strange behaviour is *only* present when a new control
is added to the Form *between* a SuspendLayout/ResumeLayout, and adding a new
combo box outside this block causes the combobox in this style to have a
visible listbox.

And since SuspendLayout/ResumeLayout are designed to improve performance, and
shouldn't change the behaviour of any control, this is a bug - even if that's a
common code path.
