Display overriden description of discriminator

Hello,

Our documentation have a Caveat scheme with discriminator named type, and number of schemes inheriting from the Caveat, eg. time, ip, asn.

The Caveat has description of type field:

properties:
  type:
    type: string
    description: Type of the caveat

Every of the sub-scheme has its own description of the type field, eg.

  properties:
    type:
      type: string
      enum: [time]
      x-discriminator-value: "time"
      description: |
        Time caveat - limits the token's validity in time.

In 1.22.3 version of ReDoc, selecting the sub-scheme caused to show its own description of type field in request body schema:

In 2.x version of ReDoc, only the description defined in Caveat is show, no matter which type is selected:

Is this a missing feature from 1.x or it's possible my schema is incompatible with new ReDoc?

I'd love to see this supported in 2.x.

Edit 1: There is a similiar issue, but I don't know if it's exactly the same: https://github.com/Redocly/redoc/issues/752

Edit 2: What is interesting, we can change type of type property eg. from string to number, and then field type changes when switching time to ip.

Reproduce the reported schema in ReDoc 2.x and compare the selected discriminator subtype with the base Caveat schema. No source file or test is named in the issue, so locate the discriminator rendering path and add coverage showing that the subtype's type-field description is displayed when switching between time and ip.
