[gestures page] bugs related to 'Situation' integration

Shards situated on the lower end of a gesture page don't open, because situations open instead.

When the text in situations is a bit longer the upper part is invisible.

#”This gesture is part of Practice…”, often does not react when clicked on. For example vitrine #2 (closed) is part of 7 walks. We can’t go to 7 Walks.'Situations' open instead.
