Describe the Bug
If you use the same id across multiple entries in a content collection, that id will resolve to the latest entry in source order
What's the expected result?
An error / otherwise louder indication of a mistake or at least documentation of this behavior of the content layer. I'm totally aware this is more my opinion than a bug proper, but I think it's fair to treat duplicate ids as a mistake, announcing as such, instead of relying on the user to understand how the underlying key-value store will handle them (happily use the id to set a record, overriding each time said is used, since the kv has no concept of uniqueness constraints).
