<SchemaDefinition> do not work with remote reference

This is a bug report

What happend

If <SchemaDefinition /> custom element points to remote reference, like below:

  description: 
     Blah blah blah.

     Below is `Foo` definition.
     <SchemaDefinition schemaRef="./shared-components.yaml#/components/schemas/Foo"/>

it fails with a following error:

Something went wrong...
Invalid JSON pointer: ./shared-components.yaml#/components/schemas/Foo

on versions

• redoc@2.0.0-rc.18
• redoc@2.0.0-rc.15

Background

I want to extract components into an external file, so it can be shared among several swagger files, like below:

• swagger-public.yaml
• swagger-private.yaml
• shared-components.yaml

Remote reference feature in standard Swagger/OpenAPI syntaxes, like below, works fine 😄

  schema:
    $ref: "./shared-components.yaml#/components/schemas/Foo"

<SchemaDefinition /> works fine if used with local reference... but fails with remote reference.
So I guess this is a bug (or a limitation) of <SchemaDefinition />

A motivation I use <SchemaDefinition schemaRef="..."/> in description is to embed a component definition into some description.
Because Redoc currently does not have schemas view unlike official Swagger viewer.

Start by reproducing the failure with the YAML example using and compare it with the working local-reference case. Trace how SchemaDefinition resolves schemaRef values, then verify that remote references resolve like the standard $ref example without breaking local references.
