Prior to this change, when in debug builds, any "proxy" (i.e. something with
unknownProperty
) would not have access to anowner
object viagetOwner(this)
. This is because of our association with theFACTORY_FOR
weakmap is only setup for the actualCoreObject
instance being created, but whenunknownProperty
exists we never expose the "real"CoreObject
instance and instead expose a native JSProxy
(so that we can trap usage ofinstance.foo
and properly error).This fix ensures that the native proxy that is returned is also associated with the factory, and can properly access
getOwner(this)
