In GetFunctionRealm, step 3.c. call
GetFunctionRealmrecursively withproxyTargetwhich assumes thatproxyTargetis a function object.If my investigation is correct, proxy exotic objects are generated in ProxyCreate and it is callable only if the
targetis callable. Thus if a function object has a target, then it is also a function object thus it isn't a spec bug. However I think add an assertion here will be helpful.
