AW.ui.combo font size

When I try to change the font size on a combo box the dropdown row height does NOT change causing a partial display of each line on the dropdown.

I changed the fon size with these commands:

ovj.getPopupTemplate().setStyle("font-size","20px");
obj.getContent("box/text").setStyle("font-size", "20px");

I have also looked through hundreds of posts on this site to find a solution with little success.

Any help appreciated.

obj.getPopupTemplate().getItemTemplate().setStyle("height", "30px");
obj.getPopupTemplate().getItemTemplate().setStyle("font-size","20px");
