Maps and item frames will break and drop if in contact with a carpet

Previously, for a number of years, I’ve had a map wall (that is to say a number of maps, mounted on item frames, mounted on a wall) that extends all the way to the floor. This floor has a carpet on it. Upon updating from 1.21.8 to 1.21.9, I found that maps are nolonger able to be placed in contact with the carpet. This causes the affected maps and their item frames to break and drop after a couple of seconds. An empty item frame is unaffected.
