Re: [csswg-drafts] [cssom] Different behavior on MediaList.appendMedium

I based my statement on the result of the last three tests:
```
log: appendMedium(','):           all, screen, not all
log: appendMedium('.'):           all, screen, not all, not all
log: deleteMedium(';'):           NotFoundError: Node was not found
```
If Gecko parsed the argument into a media query and then remove and 
add, it would not end up with two "not all"s there, and the 
`deleteMedium` call would remove "not all", right?
