Hi @cyberdave , it seems to be a bit erratic to repro – I created a copy of a site to anonymize for your review, but even before touching anything in the copy, the feature is working fine there but not in the site it was copied from. So I thought I would just anonymize the version that had the problem and send that to you for review. I changed its name in the Settings page, and voila - problem gone from that site too. (It had persisted there through multiple page refreshes and browser restarts since yesterday.)
So for now, I am not experiencing the issue and can't send you a link to repro it, so it gets a priority approaching zero, from my end and I would guess yours. If only they were all so simple
If I run into it in the future in a site that's not constrained by NDA, I'll be sure to let you know, but since others aren't seeing it and I can't repro it now, I'd check it off the list.
