MC-275657Riding a high speed minecart and using /tick sprint causes excessive lag/resource consumption and freezes/crashes the game

Reproduction Steps
- Build a looped track
- Set minecartMaxSpeed to 200
- Place a pig inside a minecart (pig is there to bypass
MC-275365) - Do /tick sprint 1000s
- After sprinting is done kill the pig and get inside the minecart yourself
- Do /tick sprint 1000s again
Observed Results
- Doing tick sprint while not riding the minecart yourself works fine
- Doing tick sprint after getting into minecraft will cause the game to freeze/crash with error code -1073740940 (sometimes -805306369)

I am unable to reproduce this, can you confirm that you are able to reproduce this issue on the latest version?
