Missing nullable Kotlin primitive generic type in inheritance

[HawkSK]

Primitive nullable Kotlin types are ignored when they are used in a generic type in inheritance.

Given

interface IReference<T> {
    val id: T
}

data class SomeDto(
    override val id: Int?
) : IReference<Int?>

generates syntactically incorrect TypeScript

export interface SomeDtoGenerated extends IReferenceGenerated<number> {
    id: number | null;
}

export interface IReferenceGenerated<T> {
    id: T;
}

whereas it should be SomeDtoGenerated extends IReferenceGenerated<number | nullable>

Plugin version: 3.1.1185

Note: Properties/fields do not have this issue. F.e. the following works as expected:

data class Dummy(val dummyField: IReference<Int?>)
