what bill said ^^^^
maybe the frame it pops into was malformed or is warped...I bet it fell out and a passerby was nice so you knew it fell off...a loser bump and run would not be so conscientious...maybe the malformed/warped receiver section gets hot from sun, expands and releases its grip on the ring?
I would not glue unless the dealer fix means something you want to avoid..let them glue it then they own it...
