        REGRESSION: In Gmail, caret reappears when dragging a selection over some text in the message body

        Functions call recomputCaretRect to see if the caret rect has changed,
        and, if it has, they invalidate (repaint) it.  recomputeCaretRect was
        returning false if the caret turned into a range selection or was blown
        away.

        * editing/SelectionController.cpp:
        (WebCore::SelectionController::recomputeCaretRect): Don't early return if
        !isCaret().  Obtain the FrameView* using the m_frame pointer, because m_sel
        may now be null.
