I'm having a very hard time understanding what problem you want fixed.
I'm guessing that you want a clarification about "display: none" applying
also to non-visual displays. I've recorded that as issue 22
   http://csswg.inkedblade.net/spec/css2.1#issue-22
But there's a lot of other text in your post here, and I can't tell if
it's trying to request some other change as well or what.
