[mediaqueries] Error handling for media-condition

https://drafts.csswg.org/mediaqueries-4/#error-handling seems only  
concerned about media queries, not so much media condition. <img sizes>  
uses a media condition, not a media query. Please state in the spec:

* What should happen when a media condition doesn't match the grammar?
* What should happen when a media condition has an unknown <mf-name> or  
<mf-value>, or disallowed <mf-value>?
* If the result of a media condition is unknown, should it match or not?
