Try to replace return target._collection[prop]
with return Reflect.get(target._collection, prop, receiver._collection)
in the get
trap. That should fix it.
I suggest you to read the Proxy, exotic object and ordinary object related parts of the EcmaScript spec to fully understand Proxy traps and JS get/set operations. It's not an easy read but I found no article that really explains these in the required depth.
As a rule of thumb, whenever you return something from a Proxy trap make sure to do it with the Reflect
equivalent that forwards all of the arguments (or their custom transformed variants) of the Proxy trap.

Yes, that works. Thanks for the help and the advice.
