------- Additional Comments from Daniel Bates <dbates at webkit.org>
I am not exactly clear on the purpose of m_mouseDownWasInSubframe. Alexey
mentioned that this instance variable was added in r3003
<http://trac.webkit.org/changeset/3003>. From my understanding of this
changeset and the current incarnation of this source code and its call sites,
it seems that the use of m_mouseDownWasInSubframe is related to some
idiosyncrasies with NSView.

There were no layout test regressions with this patch.
