<p>I would say that as it was by design, and to solve a crash, then duplicating the table to join seems a reasonable (yet not very elegant nor very handy) workaround. I would rather open a feature request asking to reinstate this functionality, or even asking the developer in the above github commit as it has not answered here.</p>
