JSchemaGeneratorInternal does not use overridden property GenerationProviders of classes that inherit from JSchemaGenerator

[joperator]

Situation:
I've implemented a custom JSchemaGenerator that inherits from Newtonsoft.Json.Schema.Generation.JSchemaGenerator and uses a fixed set of JSchemaGenerationProviders that can be extended with user-defined JSchemaGenerationProviders. The JSchemaGenerationProviders are therefore stored in a private field of my custom JSchemaGenerator that can be accessed through overridden property GenerationProviders.

Problem:
When calling one of the Generate methods of my custom JSchemaGenerator, which directly refer to the corresponding Generate method of the base class, none of the specified JSchemaGenerationProviders is used.

Code issue:
A quick look at JSchemaGeneratorInternal's GenerateInternal method indicates that it uses _generator._generationProviders instead of _generator.GenerationProviders to get the JSchemaGenerationProviders of the specified JSchemaGenerator. Since I manage the JSchemaGenerationProviders of my custom JSchemaGenerator in a separate collection and do not use the base class property GenerationProviders, _generator._generationProviders always remains null.
