Cosmetic rules can be used as CSS rules

[AdamWr]

I mean that at the moment we can also use ## instead of #$# and CSS rule will be applied.

Steps to reproduce:

1. Add this rule:
   example.org##body { background: red!important; }
2. Go to - http://example.org/

It also allows to use url(...) and if I understand correctly it shouldn't be allowed - #1026, #659 (comment)

Example:

example.org##body { background: lightblue url("https://www.w3schools.com/cssref/img_tree.gif") no-repeat fixed center!important; }

It seems that it's still possible.
Example:

example.org##body\{\}, body { background: lightblue url("https://www.w3schools.com/cssref/img_tree.gif") no-repeat fixed center!important; }
