Describe the bug

An app tab can be disabled, which are then greyed out and the user can normally no longer select hem.

However, when the app tabs do not fit into the current window, some are shown in a popup menu. The popup menu also shows the disabled app tabs and the user can still select them there.

How to reproduce

1. Show app tabs with at least one disabled tab
2. Resize the windows manually to force some app tabs to be shown as popup
3. Select a disabled tab from the popup menu

	w := a.NewWindow("TabContainer Widget")
	tabs := container.NewAppTabs(
		container.NewTabItem("Tab 1", widget.NewLabel("Hello")),
		container.NewTabItem("Tab 2", widget.NewLabel("World!")),
	)
	tabs.DisableIndex(1)
