Temporary nested cycle-tracking entries could remain in the memory set after a successful comparison. If a later sibling comparison reused one of those objects, deepStrictEqual could incorrectly fail for equivalent structures. This cleans up the temporary nested entries after the nested comparison returns. Fixes: nodejs#62422
