Created attachment 1551 [details] test Consider the attached test. In Chrome, this displays: null [object CSSStyleSheet] null while in Firefox currently it displays: [object CSSStyleSheet] [object CSSStyleSheet] [object CSSStyleSheet] The issue is whether the <style> element in the shadow tree should be loaded if it is in a shadow tree but not in the final flattened view of the document. Chrome's behaviour here probably makes sense, but it should be specified somewhere.
