I'm a Beta Tester and still had the first non public issue of RB2019 so I tested with that. The feature seems to have degraded as RB was improved up to Public V3 and worse in V4. I believe I am the only person with V4 as we were working on another issue that was very important to me.It fixed my JUKEBOX issue.
