Without looking at RocketTheme, would it be possible to change RocketTheme from:

.button {
awesome CSS here;
}

to

input[type=button], .button {
awesome CSS here;
}

The pushbutton-wide is a throwback to legacy CSS that is no longer used (so if anyone targeted that in the past wouldn't have their form styling break) and there is no CSS in the codebase for that class.
