Bug: group with only a root property and no pages still shows dropdown

[Blargian]

If you have a group with a single root property and no pages, the group still shows the dropdown icon:

{
  "group": "Quickstarts",
  "icon": "bolt-lightning",
  "root": "docs/get-started/quick-starts/home"
},

Expected behavior: The group just shows as a page would, without the dropdown icon.
