Lineboxes no longer have virtual height?

[Inactive, 2014/01/10 20:29:06]

height() is not virtual in LineBox class:
    float height() const { return isHorizontal() ? hasVirtualLogicalHeight() ?
virtualLogicalHeight() : logicalHeight() : logicalWidth(); }

+    virtual RenderObject::SelectionState selectionState() OVERRIDE { return m_selectionState; }
     void paintSelection(GraphicsContext*, const FloatPoint&, RenderStyle*, const Font&);
     InlineBox* markupBox() const;
