[Bug 23887] [Shadow] Put only the final destination insertion point to the event path

https://www.w3.org/Bugs/Public/show_bug.cgi?id=23887

--- Comment #5 from Steve Orvell <sorvell@chromium.org> ---
Thanks for the example, yes, I am not in favor of this change for the reason
stated in #3: it does not interact well with composition.

If an element host-1 like this:

<host-1>
  SR
    <host-2><content onclick="handler()">
  <child-1>

I must be guaranteed that host-1 can see events on its <content> element
independent of what host-2 does. This is necessary to preserve the integrity of
the subtree from the perspective of host-1's shadowRoot.

Note that even in this example: http://jsbin.com/IhIziHo/1/edit where host-2
entirely replaces the rendered subtree, the basic flow of events is maintained.
If child-1 fires a bubbling event, then host-1's content must see the event.
