Incorrect Request Body Schema when using both a discriminator and a $ref inside an allOf definition

[ITESMEDIA]

If you look at the "Request body schema", the definition of an unrelated definition sharing the same $ref is shown, but the "Request samples" is correct.
The issue only seems to happen if both a $ref and type using a discriminator are used inside the same "allOf" definition.

I don't quite understand what you want to achieve with discriminator.

Could you please explain your use case?

I have updated the sample with a more complete discriminator use case.
It's a simple case of a Base class (Clip) that has multiple derived classes (MediaClip and MessageClip).
The combination of everything at the same time causes the issue but everything separately is working fine.
