- fixed <rdar://problem/4613701> REGRESSION: A line break in the source HTML of a link becomes visible after drag & drop

        * page/DragController.cpp:
        (WebCore::DragController::startDrag):
        Call simplifyWhiteSpace() on the proposed link title to match what's displayed on the web page, instead of using the
        raw source HTML text.
