I found another (more simpler) code that triggers that bug:

namespace Test
{
    public class DisposeAfterLastUsageDoesNotWork
    {
        public async Task Do()
        {
            var fac = new MemoryStream();
            var bytesRead = await fac.ReadAsync(new byte[10], 0, 10);
            Console.WriteLine(bytesRead);
        }
    }
}
