Roslyn: Incorrect IDE0004 "Cast is redundant" when passing enum cast to int as constructor parameter accepting int

[Gnbrkm41]

Version Used:
Visual Studio 2019 Preview 16.0.0 Preview 1.1
(it had Resharper 2018.3 installed but the code analysis was off at the time)
Steps to Reproduce:

1. Pass an instance of enum that is cast to int when constructing an instance of a type e.g. throw new InvalidEnumArgumentException(nameof(enumInstance), (int) enumInstance, typeof(SomeEnumType));

Full code used in testing:

using System;
using System.Collections.Generic;
using System.ComponentModel;

namespace RedundantCastTesting
{
    class Program
    {
        static void Main(string[] args)
        {
            Alphabet enumInstance = (Alphabet) 110;

            //Dictionary initialiser; False positives. Initially reported in #29264, Resolved in #30245
            Dictionary<int, string> someDictionary = new Dictionary<int, string>()
            {
                [(int)Alphabet.A] = "This is A",
                [(int)Alphabet.B] = "This is B"
            };

            //Array initialiser; Working as expected
            int[] integers = {(int)Alphabet.A, (int)Alphabet.B};

            //Constructor parameter; False positives
            if (!Enum.IsDefined(typeof(Alphabet), enumInstance))
                throw new InvalidEnumArgumentException(nameof(enumInstance), (int) enumInstance, typeof(Alphabet));

            IntegerWrapper instance = new IntegerWrapper((int)enumInstance);

            //Accessing indexer; working as expected
            someDictionary[(int) Alphabet.A] = "This maybe isn't A (Just kidding)";
            string someString = someDictionary[(int) Alphabet.B];
            //Method parameter; working as expected
            SomeMethodWithIntParameter("Random string", (int) enumInstance);

        }

        static void SomeMethodWithIntParameter(string someString, int someParameter)
        {
            Console.WriteLine(someParameter.ToString());
            return;
        }

        class IntegerWrapper
        {
            public int Value { get; set; }

            public IntegerWrapper(int value)
            {
                Value = value; 
            }
        }

        enum Alphabet
        {
            A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z
        }
    }
}

Expected Behavior:
No suggestions should be made (Removing the cast will result in CS1503)
Actual Behavior:
A suggestion is made (IDE0004: Cast is redundant) when passing the cast enum instance as a parameter to type constructors.

This does not occur when using VS2017 Community 15.9.4.

It seems to be somewhat related to #29264 (Which had been resolved in #30245), but I don't see this case being tested against. Could anyone confirm that this is fixed in #30245 or not?
