Yes, it's called "burping." The rider on the MUP had it worst case, because the air volume in a 23c tire is pretty small-- so when it burped, it just went dead flat. The tire was either not fully seated to begin with, or run at far too low of a pressure.
A blast from a CO2 inflator
might have gotten it to re-seat. Shame on whatever shop sent her out on the road as a tubeless neophyte on 23c tires.
