[Feature] Need a new IsTitleBarVisibleStateTrigger

[ProJend]

Describe the problem this feature would solve

I try to run the FullScreenModeStateTrigger but it ain't catch the Tablet Mode settings that have been changed. so I just running code in class rather than XAML at this time.

Describe the solution

it can make me do something in XAML when IsVisibleChanged of Window's TitleBar has been changed.

Describe alternatives you've considered

just look like the FullScreenModeStateTrigger function.

@dotMorten isn't this what the UserInteractionModeTrigger is for? @ProJend did you try that one and it just didn't work, or did you just not find it?

Yup. Full screen and tablet mode are two different things. You can be full screen both in or outside tablet mode, and tablet mode doesn't mean things will be full-screen either.

No, it isn't what I looking for.

Well, full screen or tablet mode both can switch show state on titlebar.
