          <rdar://problem/5655160> REGRESSION (r25353): Whitespace nodes ignored between inline list items

        Test: fast/dynamic/create-renderer-for-whitespace-only-text.html

        * dom/Node.cpp:
        (WebCore::Node::attach): Added code to check if this node's renderer
        has become the "previous renderer" of any sibling text node, and if so,
        ensure that that node gets a renderer if it now needs one.
        (WebCore::Node::createRendererIfNeeded): Removed the assertion that the
        node is not attached.
