I'm looking to build a feature in my app to give user feedback if they have set their window to always show on top of other apps using a shortcut or application menu item, but find that there is a lot of hacking needed to do so. It may be more efficient to have an event listener set on the window to determine if it enters or leaves `win.setAlwaysOnTop()`

i'm thinking it would be `win.on('enter-always-on-top')` and `win.on('leave-always-on-top')`

if (is_closed_)
    return;
  WindowList::RemoveWindow(this);
  is_closed_ = true;
  for (NativeWindowObserver& observer : observers_)
    observer.OnWindowClosed();
}
void NativeWindow::NotifyWindowEndSession() {
  for (NativeWindowObserver& observer : observers_)
    observer.OnWindowEndSession();
}
void NativeWindow::NotifyWindowBlur() {
  for (NativeWindowObserver& observer : observers_)
    observer.OnWindowBlur();
}
void NativeWindow::NotifyWindowFocus() {
  for (NativeWindowObserver& observer : observers_)
    observer.OnWindowFocus();
}
void NativeWindow::NotifyWindowShow() {
