Display sidebar for "page" type

[dsa821]

I am trying to add a link to the Navbar across the top, while still displaying the sidebar on that page. The documentation states that you should add "type": "page" to an entry in _meta.json to achieve this. However, the sidebar disappears when I do that. I found this in the source which seems that the "page" type will always hide the sidebar, even ignoring the theme.sidebar settings.

Is there any way that I'm missing that I can achieve this?
