Parent/Child Relationship only visible from parent

Kudos for the nice progress with deck! Awesome to see that.

As in https://github.com/nextcloud/deck/issues/6813

Currently the relationship is only visible in the parent card. So, if you click it the child card opens, but you are more or less on a visual dead end. In reality the browser's history brings you back, luckily.

So, might be worth to have the visual counterpart in the child card at the same location where the relation is shown on the parent card.

Cheers!
