As long as the current target and the relative target are in the same tree of
trees, there must be the lowest common inclusive ancestor tree.

The current spec doesn't mention anything about what should happen if the
current target and the related target are in different tree of trees.
However, that should not happen in the context of event dispatching, I think.

Let me close this bug.
