Description Olli Pettay 2014-09-24 21:22:33 UTC 
... but ShadowRoot.getElementById() returns HTMLElement, not Element like the
DocumentFragment's getElementbyId()

Comment 1 Anne 2014-09-24 21:46:22 UTC 
Why does it override it to begin with? I think that's a separate bug.
Comment 2 Olli Pettay 2014-09-24 21:49:39 UTC 
perhaps I was unclear.
I think ShadowRoot shouldn't have getElementById, since it is there already
in DocumentFragment.
Comment 3 Adam Klein 2014-09-24 22:31:32 UTC 
Looks like the mismatched return type is only a spec bug: Blink's ShadowRoot.idl lists the return time as Element.
Comment 4 Hayato Ito 2014-09-25 02:28:58 UTC 
Nice catch.

It seems we can get rid of getElementById from ShadowRoot.
Let me update the spec.
