It will be fixed in tonight's snapshot.

As a workaround you can use the following instead of QsciLexerCSS...

class FixedCSSLexer(QsciLexerCSS):

     def description(self, style):

         if style == QsciLexerCSS.Comment:
             return "Comment"

         return super().description(style)
