Certain recursive type references are not resolved #11250
Description
Initial Checks
- I confirm that I'm using Pydantic V2
Description
Under certain conditions, Pydantic v2 will fail to resolve recursive type references and raise an error like this:
pydantic.errors.PydanticUndefinedAnnotation: name 'LegalEntity' is not defined
For further information visit https://errors.pydantic.dev/2.10/u/undefined-annotation
I've created a reproduction repo here.

Reproduction steps are in the readme.
It's worth noting that the same code works with Pydantic v1.
