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 (content_view()) {
    root_view_->RemoveChildView(content_view());
    if (browser_view()) {
      content_view()->RemoveChildView(
          browser_view()->GetInspectableWebContentsView()->GetView());
      set_browser_view(nullptr);
    }
  }
  set_content_view(view);
  focused_view_ = view;
  root_view_->AddChildView(content_view());
  root_view_->Layout();

  if (!IsClosable()) {
    WindowList::WindowCloseCancelled(this);
    return;
