Highly doubt it, as the bug relied on beacon update intervals and the fact that the glass changed upon the beacon updating, which threw it off as it was supposed to change colour, but, either there was no block above it at the moment, or was the same colour as before, confusing it. I've seen rainbow beacons on the minecraft subreddit, so I doubt it's replicable in 14w33a
