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

	"fyne.io/fyne/v2/widget"
        "fyne.io/systray"
)

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.

@andydotxyz I also just realized something that might be helpful finding out the issue.
When running the example of the fyne.io/systray repo. the Tooltip is shown also when the app is in full screen

fyne.io systray screenshot on full-screen app

my fyne app on full-screen app (no tooltip shown)

I can't paste a screenshot of the tooltip on a desktop window, because the tooltip follows the mouse pointer even when it's in screenshot mode, and this doesn't happen on the fyne.io/systray example.

From what I could see the issue should be in the difference between the loop provided by systray.RunWithExternalLoop(), and the nativeLoop used in systray.Run()

Wow - great insight but this will be a very difficult find!
