YJS's Quill binding is removing existing value

Hey, I am using yjs with quill over websockets. I noticed that yjs is ignoring the initial content from Quill and overwriting it with <p><br/></p>, anybody know how to get around this?

To clarify:
If I set value of Quill editor to something and then YJS loads, it removes that value.
If YJS was used using the same room name, it writes the value from last sync (again ignoring Qull editor value).

What will happen when the doc is no longer persisted in WS server memory? (if memory leaks or doc is timed out)
Will YJS empty out Quill editor again?
