Investigating memory leak

Hi,

I am investigating a memory leak issue we have with a Vaadin Flow app running in Spring Boot. Using the VisualVM heap dump I can see that the Collaboration Engine is holding on to view instances in “registrations”. Is there anything I need to do to unregister them?
Or is this not an issue?

In the ProductEditorView the collaboration group is used with a topic like this:
CollaborationAvatarGroup avatarGroup = new CollaborationAvatarGroup(localUser, routeLocation);
