pub fn selector_namespaced(
    namespace: impl ToString, 
    selector_classes: impl ToString
) -> String

TODO: use a real css-parser for this prepend a namespace to the selector classes, It does not affect element selector example:

use sauron_core::jss::selector_namespaced;

assert_eq!(".frame__text-anim", selector_namespaced("frame", ".text-anim"));

assert_eq!(
    ".frame__hide .frame__corner",
    selector_namespaced("frame", ".hide .corner")
);

assert_eq!(".frame__hide button", selector_namespaced("frame", ".hide button"));
assert_eq!(".frame__expand_corners,.frame__hovered", selector_namespaced("frame", ".expand_corners,.hovered"));
assert_eq!(".frame__expand_corners,.frame__hovered button .frame__highlight", selector_namespaced("frame", ".expand_corners,.hovered button .highlight"));
assert_eq!(".frame__expand_corners.frame__hovered button .frame__highlight", selector_namespaced("frame", ".expand_corners.hovered button .highlight"));
