Image option like the "Collasible" option that is not working.

Hello. I love the Antora and use for the co-worker's learning.

I want the Image option like the Collasible/Expansion's feature. I try to avoid the probrem with the "path through", but it's not working.

  1. the "Collasible" option is not working
[%collapsible]

Example block turns into collapsible summary/details.
