Controls shine through when opening the drop-down list over them.

Apparently the backgroundMode of the composite that contains the combo is set to INHERIT_FORCE

Proposed fix

The background color of the combo is set null, list-background is set to the theme default value instead.

Another proposed fix

Rüdiger, your patch would not support widget variants, since the states object passed to the ThemeValues contructor is always empty. The current implementation also does not support variants, which is another issue (states are not propagated to sub widgets). Anyway, I think that variants should be supported and therefore I'll attach a slightly different version of your patch that does so.
This patch resets the background color for the drop-down list and lets the value from the Appearance "(c)combo-list" take precedence.
