Quick info shows incorrect Dispose method when hovering over using keyword

[DoctorKrolic]

Steps to Reproduce:

using var s1 = new MyDisposableStruct(); // 1
using var s2 = new MyStruct(); // 2
using var s3 = new MyRefStruct(); // 3

public readonly struct MyDisposableStruct : IDisposable
{
    public void Dispose()
    {
    }
}

public readonly struct MyStruct
{
    public void Dispose()
    {
    }
}

public readonly ref struct MyRefStruct
{
    public void Dispose()
    {
    }
}

Hover over using keyword in all 3 cases

Expected Behavior:
Quick info shows specific Dispose method for each case (even for case 2 although it is an error)

Actual Behavior:
Case 1 - shows MyDisposableStruct.Dispose() - correct
Cases 2 and 3 - show IDisposable.Dispose() method even though neither structs implement IDisposable
