        * editing/deleting/delete-br-012.html
        
        * editing/DeleteSelectionCommand.cpp:
        (WebCore::DeleteSelectionCommand::handleSpecialCaseBRDelete):
        Update m_endingPosition when preventing merge.
        Also removed setting of m_mergeBlocksAfterDelete when this function returns true, because is is not checked in this case.
