How do Respawn Bubbles work?

[arsenicBumpnip]

Some of the Rift challenges are "Free an ally from a Respawn Bubble".
When I jumped off the edge, it put me in a bubble that my buddy had to punch a few times to get me out of it. But when he jumped off the edge after that, he just respawned normally, and every time we've tried it after that (including making sure the AI hit us off the edge to see if that was the issue) we just respawn normally.
Is there a specific trick/condition to getting it to trigger or is it just random chance on death?

I like how you answered your own question.

It's fine to say "I don't know" or just not reply if you don't have anything constructive to say, y'know.
Nowhere in my post does the answer to "is the bubble a random chance on ringout or is it only triggered by specific conditions?" lie.

It seems to be that the host can't get the bubble only your partner, did some test and this was the only solution. Just do it twice I guess...
