If you pick up an item in tick freeze, see MC-267201 and MC-267190 on how to do this, there will be no pickup animation played. This is expected. However, if you turn off tick freeze the item picked up will come back to you, as fast as it can. It will have the hitbox for the item coming to you as well, and the item will come to you no matter how far away you are. This creates what I call an extended pickup animation (There's probably an actual name for it but I can't find it)

I have attached a video, however the bug is only there for a few frames so I have also attached a screenshot

Steps to reproduce:

1. Reproduce either MC-267201 or MC-267190 to pick up the item in tick freeze
2. Turn on hitboxes with F3+B
3. Walk away from where you picked up the item
4. Turn off tick freeze with /tick unfreeze
5. The item pickup animation will play. The animation will begin at the point you picked up the item in tick freeze and end at the player. There is no distance limit
