Description Dominic Cooney 2013-06-03 00:34:13 UTC 
The effect applyAuthorStyles is described thus: " If false (default value), the author styles are not applied to the shadow tree."

This presumably means that even if an element in Shadow DOM has a custom pseudo ID, author styles using that pseudo ID don't affect it.

Is this intended? It is simple to understand but seems counterintuitive.

I think this is a problem. We should expose ::part styling to enclosing scopes.

See this bug for a proposal:

This is just poor wording in the spec. We need to describe switching applyAuthorStyles to "true" as purely additive to the defaults.

Closing this issue because applyAuthorStyles was dead.
