The onExternalClick custom hook keeps a reference to elements that may
no longer be in the DOM, this can cause entire sections of the DOM that
are no longer needed to be kept in memory, and can also retain the
associated Owl components and their data.
To solve this, we set the downTarget and upTarget to null after calling
the callback. In practice they are no longer used in the code but we are
keeping it for stable compatibility.
