Created attachment 285767 [details] Run in Safari TP I'd expect complex selectors such as: :host > div { ... } or :host(.foo) > div { ... } to work in a style inside a shadow root. Repro: http://jsbin.com/sinidob/edit?html,output Tested in Safari TP, Chrome stable works as expected.

Created attachment 286054 [details] patch This enables :host(.foo) div { ... } but doesn't cover :host::after { ... } case.
