`JsonValue` can receive `type` but not `interface`

[fregante]

import {JsonValue} from "type-fest";

declare function identity(value: JsonValue): JsonValue;

interface InterfaceObject {
    origin: string;
}

const objectViaInterface: InterfaceObject = {
    origin: 'red'
};

identity(objectViaInterface);
// Argument of type 'InterfaceObject' is not assignable to parameter of type 'JsonValue'.
//   Type 'InterfaceObject' is not assignable to type 'JsonObject'.
//    Type 'InterfaceObject' is not assignable to type '{ [x: string]: JsonValue; }'.
//      Index signature for type 'string' is missing in type 'InterfaceObject'.(2345)

type TypeObject = {
    origin: string;
}

const objectViaType: TypeObject = {
    origin: 'red'
};

identity(objectViaType) // Fine

Jsonify "fixes" the issue in some cases but it breaks in other

In my case I'm using extends OmitIndexSignature<JsonValue> and that silenced the issue for now.
