Holding the jump key while on a bouncy block (beds, slime blocks, etc.) does not reduce the hunger bar. This effects normal jumps and sprint jumps.

Observed Behavior:

Repeatedly jumping on a bouncy block will not reduce hunger.

Expected Behavior:

Jumping on a bouncy block will reduce hunger by the same amount as if on any other block.

Steps to Reproduce:

1. Create and load a new creative world with cheats enabled.
2. Write the following command in an active, repeating command block:

   /tellraw @p ["Exhaustion: ",{"entity":"@p","nbt":"foodExhaustionLevel"}]

3. Obtain a slime block and place it under you.
4. Switch to survival mode.
5. Hold the jump key to repeatedly jump on the slime block
   → Your food exhaustion level remains the same.

Note:

The bug only happens if the player is jumping repeatedly. Jumping while previously stationary will reduce hunger like normal.
