and if it really bothers me some tape or some clear nail polish should fix it.
It is possible that clear nail polish will do very little to mitigate the problem. At those frequencies, capacitive coupling can be as good as a DC conducting path. The bumper adds a millimeter or so of space which reduces the capacitive coupling as compared to nail polish.
