I don't know if it's on purpose or not, but document.body!!.style.overflow = "hidden" doesn't works.

This works :

    document.body!!.style.overflowX = "hidden"
    document.body!!.style.overflowY = "hidden"

I expected that setting style.overflow set style.overflowX style.overflowY to the same provided value but I got an unresolved reference instead
