Native Button and Caption alignment

I made a Native Button that is taller then than the default but I want the caption to be more aligned higher up so I can use the bottom to emphasize the extra space there with a background image.

I’ve been at it for a while and can’t seem to figure out how to get the text higher up on the Button. Any ideas?


As a workaround I did the following:

setCaption(caption + "<br>&nbsp");

Would like to figure out how to fix this in css but this will do for now.
