I believe it's worth mentioning EF is capable of detecting replacements of owned entities.

### Type of issue

Missing information

### Description

If an instance of an owned entity is replaced with a new instance that has the same primary key, EF will detect the replacement and issue an update.

In contrast, if this were a regular navigation property, EF would raise an error, indicating an attempt to track multiple entities with the same identifier.

This highlights a significant difference in behavior between HasOne/HasMany and OwnsOne/OwnsMany.
