Hanumatan jumping in air repeatedly... bug or?

Several times I have gone into the new Hanumatan Guardian Raid and experienced this period where he just repeatedly jumps in the air and lands (ya know, the one where if you get hit by the slam, he does an additional attack). When it happens he just does that same pattern over and over and it has happened more than 5 times in a row back to back. Is this a bug or is this a pattern that needs to be nerfed like Caliligos?
