  • 1

    Buggy. E { F {}} doesn’t work, but E { & F {}} does.

  • 2

    Buggy. The syntax is supported, but nested selectors are prefixed by the webmail, which might invalidate the selector.

  • 3

    Not supported. The nested selectors are removed, making the nest properties apply to the parent selector.
