Weird text input box focus style on Starz #20
Description
Input boxes in the settings popup look weird when focused on Starz.
It's because of a border-bottom-color rule. We normalize the base element styles, but not the :focus styles. I think I didn't want to use !important because that might interfere with user agent styles? I think if we add :focus to the normalization rule's selector, it will revert Starz's author stylesheet but not the UA style. So that's probably the right way to do it.
