The CSS inside the {}s all seems fine (other than some vendor-specific prefixes that may not be necessary any more), which is why I ended up focusing on the selectors.
Looking through the Stylish source, I think "tooltip" (without a class or id) is a Stylish invention. It's not a standard HTML tag/entity, so I suspect Stylish is doing some preprocessing similar to the above--or Firefox gave them access to some underlying presentation (XUL?) that can't be expressed in CSS.
