I filed a bug for this behavior in WebKit, and one of the responses was the
following:

My personal opinion is that you should have to cancel the drop event to
prevent the drop's default action, but apparently the IE model does not
agree (I didn't test this personally though). Is the divergence between IE
and the spec intentional?
