        * rendering/SVGRootInlineBox.cpp:
        (WebCore::SVGRootInlineBoxPaintWalker::mayHaveSelection):
        Use InlineTextBox::selectionStartEnd() instead of
        RenderObject::selectionStartEnd() because latter may span multiple
        comparing startPos and endPos is irrelevant in some cases.
        former selectionStartEnd() is for single line and comparing
        startPos and endPos will make sense.
