Just to confirm: You don't want to add this to the parent class, right?

[tasak, 2015/08/28 03:58:36]

Right.

DocumentResourceClient is one of difficult classes to add
WTF_MAKE_FAST_ALLOCATED.
Because SVGUseElement is DocumentResourceClient.
c.f.
class SVGUseElement final : public SVGGraphicsElement,
                            public SVGURIReference,
