Description Takashi Sakamoto 2013-07-24 06:05:49 UTC 
Since styles in shadow trees can select host element, we should clarify apply-author-styles of shadow roots of the host element.

for example,

style id="style0"
    #host { border: 1px solid blue; }
div
    #shadow-root
        style id="style1"
            #host { background-color: red; }
        div id="host"
            #shadow-root[apply-author-styles=true]
                style id="style2"
                    #host { background-color: green; }
                div

- The shadow root of div#host has apply-author-styles true.
- The shadow root containing div#host has apply-author-styles false.

My concern is whether styles in style#style0 will match div#host or not.

Currently, I think, "match".

Closing this because apply-author-styles was gone.
