.Net: Bug: C# Content filtering annotations missing

[rsaundersbdo]

Describe the bug
When receiving a 400 content filter exception from sending a message to an Azure OpenAI model the inner exception that is supposed to include the reasoning for the exception is null.

To Reproduce
Steps to reproduce the behavior:
1.Setup an Azure OpenAI model with content filter set to block on message inputs.
2. Send a streaming message request that would trigger the content filtering to the model.
3. Inspect the expectation and see that the inner exception is null.

Expected behavior
The inner exception is expected to be populated with the information on why the message was blocked.

Just to add a bit more context

when we get a 400 back we also get this Response Body, for some reason this is not returned, wondering what might be occluding the information or this is lost in the Azure SDK...
