I was using the ThemeRoller to aid in the customization of a jQuery mobile theme, but changing the “Default Icon” to black doesn't seem to do anything, while everything else works (for example removing the circle). I have tried with both Chrome and Firefox, and the console doesn't give any javascript errors anyways.

I know I can have black icons by adding the .ui-alt-icon class, but it's a hassle to do it on every element, and it is especially an hassle if I want to have the default icon under a child element with an .ui-alt-icon. I could change the icons.css manually, but that's the whole point of the theme roller isn't it?

Is it a bug or I am doing something wrong?
