Entity movement behavior different from vanilla when last collision shape reduces movement to less than 1e-7

The issue is splitted from #442

Instructions

The following tnt duper behavior changes when the tnt entity is nearby a chunk border

Reproduction Steps

1. Install fabric-carpet mod

2. Build 2 of the tnt duper in the following image in a correct direction

   • The coordinate of the sticky piston are -2 -58 59 and -12 -58 59

   

   

3. Use fabric-carpet's command /carpet hardcodeTNTangle 4.457099494579702 to override tnt initial velocity

4. Activate the tnt duper with 4gt pulse every 8gt

Behavior

Expected behavior: Both of these 2 tnt dupers launch tnt on retract (this is also the vanilla behavior)

Actual behavior: The left duper in the image doesn't launch tnt, which behavior wrongly. Only the right one launch tnt

Version Information

Reproduced with

MC version	lithium version	carpet version
1.18.2	0.10.3	1.4.66
1.19	0.8.1	1.4.79
1.19.3	0.10.4	1.4.93

Other Information

The behavior is locational. The wrong behavior only happens nearby chunk border

The wrong behavior should be reproduce-able with only lithium, if you test it long enough and wait for a tnt to be created with the special velocity

Example wdl (1.18.2): void.zip

Tested with older mc versions after applied the fix (https://github.com/CaffeineMC/lithium-fabric/issues/442#issuecomment-1402417016) of #442. This issue still affect the following versions

MC version	lithium version	carpet version
1.16.4/5	0.6.4	1.4.44
1.17.1	0.7.5	1.4.56

For block collisions this is fixed by https://github.com/CaffeineMC/lithium-fabric/commit/61f1471b321367a5e470964a6d51daa41aa71221

For entity collisions (boats & shulkers) this is still an issue

Should also be fixed for entity collisions now, but not 100% sure
