Properly set the username for federated editing

If NextcloudServer1 user "jon" jon@nc.tld1 opens document via other server running Collabora, then a different guy named "jon" on NextcloudServer2 jon@nc.tld2 opens a document, the Collabora admin panel counts these both as 1 user in the "Users online" tab. It says correctly in large letters, that there are 2 users, but the "Users online" Collabora Admin tab @loleaflet/dist/admin/admin.html combines any users with the same name even though they are different people.

I'm wondering if there's anyway to include the domain in the username that gets sent to collabora server or if this has another workaround, or is this a Collabora bug or perhaps there's a loolwsd admin setting I can't find. I deem this NOT good for the purpose of monitoring usage for 2 NextCloud instances sharing a Collabora server.

Start with loleaflet/dist/admin/admin.html and trace how the Users online tab identifies and combines users. Then inspect how the username is sent to the Collabora server and whether the federated domain is available there. Done means users with the same name from different Nextcloud domains are counted separately.
