(From update of attachment 143440)
While I'm no shadow DOM expert, I feel that this patch needs more explanation of what's going on.

Why are we skipping over StyleElement::insertedIntoDocument/removedFromDocument? That will not only prevent document.styleSheets from exposing the sheet, but also prevent StyleElement from parsing the sheet, and StyleResolver from applying any of its style (since it gets its sheet data from there.)

Maybe <style> elements are supposed to just hang dead inside a shadow subtree?
