VerificationException static virtual interface methods, and generic constraints

[vyacheslav-volkov]

Description

I found code that throws a VerificationException for static virtual interface methods, and generic constraints, similar to this issue #73658 but without reflection.

Reproduction Steps

Run this code:

public interface ITestItem<T>
{
}

public interface IStaticInterfaceBase<T, in TRequest>
    where T : class
    where TRequest : IStaticInterfaceBase<T, TRequest>
{
    static abstract void TryInvoke<TItem>(TItem item, TRequest request) where TItem : ITestItem<T>;
}

public interface IStaticInterface<T, in TRequest> : IStaticInterfaceBase<T, TRequest>
    where T : class
    where TRequest : IStaticInterface<T, TRequest>
{
    static void IStaticInterfaceBase<T, TRequest>.TryInvoke<TItem>(TItem item, TRequest request)
    {
    }
}

public class Request : IStaticInterface<object, Request>
{
}

internal class Program
{
    public static void Invoke<T, TRequest>(TRequest request)
        where T : class
        where TRequest : IStaticInterfaceBase<T, TRequest> =>
        TRequest.TryInvoke((ITestItem<T>) null!, request);

    public static void Main(string[] args) => Invoke<object, Request>(new Request());
}

Expected behavior

The code will run without error.

Actual behavior

Unhandled exception. System.Security.VerificationException: Method StaticInterfaceBug.IStaticInterface`2[System.Object,StaticInterfaceBug.Request].StaticInterfaceBug.IStaticInterfaceBase<T,TRequest>.TryInvoke: type argument 'TItem' violates the constraint of type parameter 'TItem'.

@trylek Could this have the same underlying cause as the other issue?
