Does prosemirrorToYXmlFragment really lose hystory?

[remorses]

The prosemirrorToYXmlFragment documentation says "note that this function should not be used to rehydrate a Y.Doc from a database once collaboration has begun as all history will be lost"

But reading the code it doesn't look like the yjs doc history is being lost, it seems it applies any update from the prosemirror node to the yjs doc, am i right?
