Unit frame bug when running Loot Master group

There has been a bug in Classic TBC, seemingly since launch, that causes unit frames to become unresponsive (even name targeting functions in chat - like clicking a name to do a player invite) after a Loot Master distributes any loot using the Loot Master tools. I can’t find any posts referencing this bug. Is this being worked on?

The loot master in each of our raid teams has to /reload each time after they loot something to someone if they want to be able to, for example, invite a new raider, make someone a raid assistant, use the raid target markers (clicking on portraits), leave group by clicking a portrait, etc. There’s a laundry list of unit frame things that break the instant you master loot anything and the bug is very disruptive to raiding. Would love to hear that it’s nearly fixed!
