I would think that would be pretty common with hard acceleration on small, torquey, lightweight bikes with huge rear sprockets like you see in the YouTube videos of the gymkhana competitions. As Motor-G-man said, good riders will be shifting their weight around to move the C.G. forward and reduce the tendency of the front wheel to lift under power, but with enough throttle and/or appropriate gearing, the rider's weight might not be enough to keep the front tire planted.
