Show mutual rooms/subspaces under space they belong #2517
Description
Describe the problem
Spaces and rooms that are related shows separate when checking mutual rooms in user profile. It only looks cluttered when there are a lot of mutual rooms with users.
Describe the solution you'd like
It will make more sense to show rooms and subspaces together under the main space. Further those main spaces can be collapsed showing the mutual rooms in a nice presentable form.
