[GAMEPLAY] Jhin refuses to dance during Sona's Crescendo

Sona ult doesn't work on Jhin sometimes; he walks right through it even though his nearby teammates stop to dance a jolly jig.

I haven't tested what the necessary conditions to trigger this is. Crescendo's visual effects will go through Jhin but he won't be stunned. It has happened in two different games, in both games the Jhin had neither banshees, qss, cleanse or morgana, and his support did not have mikaels either, however in both cases there was another champion who was stunned by the ult.
