[Code Quality] Nonmatching DOM tree in Summer School page

[eddybrando]

Steps to reproduce the problem

1. Start the project locally
2. Go to the /events/summer-school page

What is the current behavior?

Whilst in local development, the /events/summer-school page reports an issue:

[Vue warn]: The client-side rendered virtual DOM tree is not matching server-rendered content. This is likely caused by incorrect HTML markup, for example nesting block-level elements inside <p>, or missing <tbody>. Bailing hydration and performing full client-side render.

What is the expected behavior?

The client-side rendered virtual DOM tree should match the server-rendered content.

This issue is still present in the local development environment:

There is no longer a summer-school page, but also neither http://localhost:3000/events/summer-school-2022/ nor http://localhost:3000/events/summer-school-2023/ show this issue anymore.
