CSSUnkownRule is also very important for (wysiwyg) content editors.
Let's imagine my content editor is built on webkit; it does not
understand -moz-* properties but as a content editor, I am not building
websites for webkit only so I really really want my -moz-* declarations
to be preserved when I load a document, edit and reserialize stylesheets
or save the document.
CSSUnknownRules has flaws, but we still need a way to preserve whatever
is dropped by the CSS parser.
