Going up on stairs with autojump drains saturation and the hunger bar!

This bug is VERY old and unnoticed, since sprinting and the hunger bar were added, this bug is present: when the autojump setting is on and the player goes up on stairs, the autojump acts repeatedly in a REALLY short amount of time, this leads to a drain in the hunger bar, it can drain a whole bar in just 50 SECONDS or even less.

 

 

I don't know if this bug is present on the Java Edition as well.
