MKS/PTC Implementer users only: Work with Objects - F16 switching between "native" and IFS objects behavior buggy?

For those of you using Implementer and utilize IFS objects:
When using option 11. Work with Objects, do you find switching between the default non-IFS objects and IFS objects is buggy?
Starting Work with Objects in "non-IFS" mode, you'll see your native objects. Panel WRKOBJ.1 has the title "Work with Objects". Press F16=Show IFS Obj, and you'll be taken to panel WRKOBJ.1I "Work with IFS Objects" showing the native objects.

PTC support has article CS180868 which identifies the issue, but the resolution is "Reported to R&D as RFC 145092/SPR 5345150". It applies to Implementer v11.0 forward, so they've known about this for a LONG time (10+ years?). We're seeing it on v12.5 and v12.6. I created a case, and the response was " Thank you for notifying us. We have an SPR logged for this issue and have attached you to it. You will be notified when this is addressed." Which is the Implementer support team's polite way of saying "It sucks to be you."

(BTW, does anyone know whether Dawn B. is out at PTC? For the past few months, I've been getting responses from Brian Anderson, "Technical Support Manager".)
