return handle_scope.Escape(Local<Value>::New(
isolate,
MakeCallback(env, recv.As<Value>(), callback, argc, argv)));
Environment* env = Environment::GetCurrent(callback->CreationContext());

callback->CreationContext() seems a little more correct than recv->CreationContext() because the former is the context the actual callback takes place in but it's admittedly a mostly academic difference.

LGTM

Check that invoking a callback on a receiver from a different context
works.

It ran afoul of an `env->context() == isolate->GetCurrentContext()`
assertion so retrieve the environment from the callback context and
the context to enter from the environment's context() method.

We could also have retrieved the environment from the receiver's context
and that would have made little practical difference.  It just seemed
more correct to get it from the callback context because that is the
actual execution context.

@gibfahn I think this is good to be backported too.
