about slash in background property

[pseudorasbora]

hi,
When a “slash” is included in the “background” property of a stylesheet, the style is removed.
e.g :
<div style="background:url(xx.jpg) 50% 50% / cover;"></div>
used in version 8.1.844-beta.
thanks

This syntax seems to be unsupported by AngleSharp.Css currently.
