I think the proper fix is to infer_dtype for letting it handle EAs correctly (#23553), but fine with this as a stop-gap for 0.25.1

Yah, the fix I'm working on locally makes infer_dtype handle interval correctly. Getting all EAs right is out of scope.

ok, can you make an issue to fix the doc-string in infer_dtype. is possible to handle this inside infer_dtype rather than raise? or is this meant as a tactical fix?
