This was caused by the element getting cached on the class before the
Vue app has finished rendering.

Closes #43560

The frontend code doesn't use this so there's no practical point in
supporting this. We also hardcode the limit to 20 so users can no longer
request their own limit, which could overload the database (depending on
any upper bounds perhaps enforced by Kaminari).
