Windows: Command ChangeCanExecute does not re-enable a disabled button

[Keflon]

Description

UWP only: When binding an ICommand to a Button, if the ICommand disables the Button (e.g. during an await) and then re-enables the Button, the Button is drawn as if it is still disabled.

Steps to Reproduce

1. Create a Command with the following handlers:

    private async void DoDelay()
    {
        PreventDelay = true;
        DelayCommand.ChangeCanExecute();
        await Task.Delay(1000);
        PreventDelay = false;
        DelayCommand.ChangeCanExecute();
    }

    private bool CanDoDelay()
    {
        return !PreventDelay;
    }

2. Bind the Command to a Button.
3. Click the Button.
4. On UWP, the Button remains disabled after the delay completes.

Can reproduce the issue in the latest version but not in the current net6.0 branch.

The issue should be fixed in the upcoming release.
