This is similar to how Gecko avoids a reference cycle, where both the NamedNodeMap and Attribute would otherwise store a strong reference to their associated Element. Gecko manually clears stored raw references when an Element is destroyed, whereas we use weak references to do so automatically. Attribute's ownerElement getter and setter are moved out of line to avoid an #include cycle between Element and Attribute.
