No tags in page block

I am currently trying to build a landing page for my theme, where a static page is used to fill it with content. What I want is to give the page tags and load posts which have the tags as primary tags. However I can’t get the tags helper to give me any output. When I try the same in the {{#post}} context, with a post, it works fine.

I tried several different route.yaml configurations, long form with {{#post}} block and short form with {{#page}} context. I can access other data except {{author}} and {{tags}}.

routes.yaml

routes:
  /:
    template: index
    data:
      post: page.home

index.hbs

{{#post}}
{{#is "page"}}
      {{content}}
      {{author}}
      {{tags}}
{{/is}}
{{/post}}

I use the current ghost version selfhosted on a local install.
