📄 Description

This fixes issues when a mapping/listing delegates to another mapping/listing.

The core issue is that cachedValues is not guaranteed to be the complete set of the object's members; they may be stored on the delegate instead.

Therefore, it's not correct compute hash code and equality based on cachedValues. Instead, it's better to use the getCachedValue() method, which has the correct logic for looking up the existing cached value.
