Suggestion view is not connected to the original document

[martinRenou]

So the sceneL is not connected to the original document anymore, meaning if another collaborator changes the base document without making a suggestion, it is not reflected in sceneL unless they refresh the page. We may consider this as a bug? Happy to merge the PR as is anyway and we can iterate upon.
