Actually i think that assertion would be incorrect, but likewise i think
m_documentUnderMouse would be wrong, take the following:

1. I start to drag content over an element
2. page load occurs, resulting in a new document
3. i drop

now the issue will be the m_documentUnderMouse will be bogus, and i think
that's actually the underlying problem.
