I think the spec should address these issues and define the well-defined
behavior clearly. The current spec looks too lazy because it only mention
the following:

> Window object named properties [HTML] must access the nodes in the
document tree.

I think this is not enough to achieve the interoperability among UAs.

I've discussed this topic several times in Google, however, this is still
an unsolved problem.
We don't have anything which we can upstream to the spec yet.
In Blink, we've supported only "Copy" for a selection which spans shadow
boundaries.
Any ideas are highly welcome.
