[csswg-drafts] [css-conditional][quirks] Quirks mode and @supports/CSS.supports

svgeesus has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-conditional][quirks] Quirks mode and @supports/CSS.supports ==
from https://lists.w3.org/Archives/Public/www-style/2015Nov/0338.html by @zcorpan 

> What is the interaction between

> https://drafts.csswg.org/css-conditional/#at-supports
> https://drafts.csswg.org/css-conditional/#the-css-interface

> ...and...

> https://quirks.spec.whatwg.org/#the-hashless-hex-color-quirk
> https://quirks.spec.whatwg.org/#the-unitless-length-quirk

> Testing in  
http://software.hixie.ch/utilities/js/live-dom-viewer/saved/3765 it  
appears that in Blink/WebKit/Gecko apply the quirks in @supports, but not  
in CSS.supports(). Presto doesn't apply the quirks to @supports and  
doesn't have CSS.supports(). I haven't checked IE/Edge. I suggest we  
specify what Blink/WebKit/Gecko do.
