Is there a plan to support the null type in OAS 3.1?

One of the changes from OpenAPI 3.0 to 3.1 was removing the nullable keyword in favor of allowing type to be an array, and having null as a type there. The places our schema uses this seem to render in the docs unexpectedly, as "nullstring" in the response detail view, and ""Unknown Type: null,string"" in the example response.

null is not listed in the docs as a supported data type - is that expected to be added as part of OAS 3.1 support?
