I've finally found Destiny 2's version of superbouncing.. (Destiny)
... by accident, and likely not reproducable : p
edit: 10:05am: It might actually be reproducable? Someone I know has reproduced it on a different area with the barriers
As noted in video description, I ended up in an empty version of the strike's "protect Ghost" room, and couldn't escape out either end, so had to fast travel.
But yeah, for some reason, loading into a new area, connection breaks, for some reason game puts me up way into the skybox.
