Created attachment 205205 [details] Screen shot: shadow DOM of video controls appear to stop at one nested level deep See screen shot. The shadow DOM of video controls appear to stop at one level deep. This is either a functional bug in that nested shadow DOM content is not displayed in the Web Inspector, or it's a UX bug that could be resolved by calling this "Shadow Content (empty)" or something to that effect.

So, data:text/html,<input%20type="button"> shows there is no subtree. I'm not sure if it is correct or not though.
This is correct, the Shadow DOM tree is empty for these buttons. We probably should not show it if it is empty.
This works fine for me on trunk.
