This page does not display a link to itself in the RHS menu. When edited, the Menu settings tab shows that it does have a place in the microsite's menu structure - which is essential if any sort of automatic RHS menu is to appear - but viewing the Dashboard | Menus shows that this has been disabled.

Disabling it in this way also has the effect of changing the RHS navigation panel heading from a linked 'A sample microsite' to an unlinked 'In A sample microsite'.

Compare this with the similar page called 'An ordinary page on the sample microsite', which is enabled in the Dashboard | Menus.
