Disabling a MenuFlyoutItem loses it's style when theme != application defualt

[DHancock]

Describe the bug

If you change a MenuFlyoutItem's state to disabled inside the menu item's ICommand.Execute() implementation by calling it's ICommand.CanExecuteChanged.Invoke() method, while the app's theme is dark and the default system theme is light, the next time it's containing menu is opened the MenuFlyoutItem text is drawn with a black foreground, irrelevant of it's style.

Steps to reproduce the bug

1. Run the attached project with the system theme set to light.
2. Click the toggle theme button.
3. Open the Demo menu.
4. Note that the last MenuFlyoutItem is current enabled.
5. Select that menu item.
6. Reopen the Demo menu
7. The last menu item is now drawn in black.

Additional context

This bug is in 1.4.1 and 1.4.0 releases.

The only work arround I have found is to delay calling Invoke() so that it's not called from within the Execute() method. For example in the repro project:

    private void ExecuteMenuCommand()
    {
        DoWork();

        Task.Run(() =>
        {
            TestCommand.RaiseCanExecuteChanged();
        });
    }
