This updates the cache objects to use Weakmap instead of Map in order to prevent potential memory leaks. Maps treat the objects used for keys as a new reference, if the original reference was deleted there would be the reference in the key which would not be garbage collected. Using a Weakmap this reference would be garbage collected when the original reference is removed.
