.list.disc > li::marker{color:red}

// parse this css rule
var styles = parser.Parse(css);

rule.SelectorText

I will get the selector,but the prop SelectorText is null! If the style rules has ":marker".
I can not fix this.help me please!

var stylesheet = parser.ParseStyleSheet(css);

var rule = stylesheet.Rules[0] as AngleSharp.Css.Dom.ICssStyleRule;

Console.WriteLine(rule.SelectorText);
