Creeper Explosion Radius can't be negative on Paper

[PumpkinKnightStudio]

Expected behavior

While using this following command in
Vanilla: summon creeper ~ ~ ~ {ExplosionRadius:-1b,Fuse:0} will create an explosion
Paper: summon creeper ~ ~ ~ {ExplosionRadius:-1b,Fuse:0} the creeper will not explode

This is commonly used in Player Launch Datapack

Observed/Actual behavior

The creeper should explode, applying the motion to player

Steps/models to reproduce

Use this command: summon creeper ~ ~ ~ {ExplosionRadius:-1b,Fuse:0}
While ExplosionRadius is negative, it will not explode

Other

Since this is used by many datapack to launch player, I believe using ExplosionRadius:-1 should be possible

It seems that spigot explicitly clamp the radius to 0.
