Another RxUI bug?

gistfile1.cs

[Fact]
public void CanStartGameWithThreeOrMorePlayers()
{
    foreach (var i in Enumerable.Range(1, 7))
    {
        viewmodel.NewPlayerName = "Player" + i;
        viewmodel.AddPlayer.Execute(null);
        
        // Test passes with this assert present, fails with it commented out
        //Assert.Equal(i >= 3, viewmodel.StartGame.CanExecute(null));
    }

    Assert.Equal(true, viewmodel.StartGame.CanExecute(null));              
}
