The spec is: https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#active-element The current implementation of the ShadowRoot.activeElement does not use the result of re-targeting algorithm. If a distributed node is focused, shadowroot.activeElement should return the distributed node, but i returns null wrongly.
