When you preview a looping particle, all particles are killed when the emitter expires, this is annoying when you preview particles that will loop in-game, where minecraft only kills particles when the particle itself expires.
Noting here that this was observed with a particle using events to combine particles together. (multiple emitter spawn events when the "main" emitter spawns)
