Calling window.Perform(system.ActionRaise) does not show the window on
the top if the app is currently not active. This can happen for example
if the app integrated with systray (https://pkg.go.dev/fyne.io/systray)
where the menu item launches a window, the window is not showing at the
top. It is fixed by activating the current app if necessary.
