I saw it live yesterday (on the stream), and recall the only other time having seen it is when there was a camera in the pocket and the balls were bouncing off of it. It used to happen a lot (relatively speaking) on old MR events from the 2000's. There is a famous case of it happening twice in a row by 2 players on the same table, and when the first came back to shoot the same ball a THIRD time, he slow rolled it. I'm sure someone remembers and can link. In that case though it was the camera's fault. This one is the table design.
I've also never seen it on a GC in actual play. I do drills on my home table to the same pocket, and it really takes a full pocket for a ball to pop out.
