Describe the bug

I have configured my fyne app to show a tooltip using the systray.SetTooltip("tooltip") method.
I can correctly see the tooltip when I hover on the sytray icon when the systray bar is shown on a Desktop window (on both monitors in my dual monitor setup), however when I hover on the icon in a space (full windowed app), the tooltip is not shown

How to reproduce

1. Start the fyne app
2. while a desktop pane is active hover on the icon: the tooltip is shown
3. maximize an app
4. while on the scene with the maximized app hover on the app icon: the tooltip is not shown

)

func main() {
	a := app.New()
	w := a.NewWindow("SysTray")
        a.Lifecycle().SetOnStarted(func() {
	      systray.SetTooltip("test tooltip")
        })
	if desk, ok := a.(desktop.App); ok {
		m := fyne.NewMenu("MyApp",
			fyne.NewMenuItem("Show", func() {
				w.Show()
			}))
		desk.SetSystemTrayMenu(m)
	}

	w.SetContent(widget.NewLabel("Fyne System Tray"))
	w.SetCloseIntercept(func() {
		w.Hide()
	})
	w.ShowAndRun()
}

I have checked this out and you're right.
However all the other apps I have installed have the same restriction (Dropbox, Docker etc).

I think this may be a "feature" of macOS...

Jetbrains Toolbox doesn't have this behavior, and shows the tooltip even on full screen, so I don't think it's a restriction on MacOs side, but definitely it looks like they expect something different to be set, because also in my case, many other apps do not show the tooltip.
