The `deepCopy` utility function previously set its internal tracking symbol property to `undefined` after completion. However, this still caused the property to exist with a value of `undefined`. Jasmine 4.1 now checks for symbols with its `toEqual` expectation which resulted in failing tests. The internal tracking symbol property is now removed instead via `delete`.
