Layer panel doesn't reflect change of material - R8 bug

I had a material called “Leather dark brown” assigned to Leather layers in my model. I replaced the material assignments with “Kojak Project Body Leather”. The new assignment is operational and shows in the model, but the Material name in the panel is still the old material. Placing the cursor on the old name reveals the new name…

I have to close and reopen Rhino for the correct name to show up.

Rhino 8.15.24345.18001, 2024-12-10

(In case it is significant, the new material is an .sbsar.)
