:hover throws in SelectorEvaluator.visitPseudoClassSelector #1079
Description
When parsing an element with the hover attribute (such as a a:link:hover for example), SelectorEvaluator.visitPseudoClassSelector throws.
I'm not sure if this is because hover is not an official selector as per MDN documentation, but this is still annoying as it is a regular occurrence.
Being given the choice to simply return false would be nice.
