Summary:
Running "/tick freeze" then "/tick sprint N" will advance the game by N+1 ticks.

Steps to reproduce:

1. Build a tall scaffolding pillar.
2. Run "/tick freeze".
3. Break the bottom scaffolding.
4. Run "/tick sprint N".

Expected result:
N scaffolding break.

Observed result:
N+1 scaffolding break.

Impact:
In case it’s not clear that "/tick sprint" should be accurate to a single tick, I’d like to point out that this is a maddening bug when trying to measure redstone timing. I’d also argue that accepting a tick-precise sprint duration is a reason for actual behavior to also be tick-precise.

Tested in:
1.20.4 and snapshot 24w05b
