This issue is also affecting the admin sidebar.

It looks like it has been like this since: [UX: Sections not collapsable in "header dropdown" navigation menu by tgxworld · Pull Request #21604 · discourse/discourse · GitHub](https://github.com/discourse/discourse/pull/21604)

The problem is that we’re forcing the sections to be collapsable in mobile view or narrow screens when the navigation menu is set to `header dropdown`, but we’re not handling the case where it is set to `sidebar`.

To address the issue, I believe we should force the sections to always be collapsable when in mobile mode or on narrow screens.

The PR below should fix this:
