[MCPE-106192] Spawned projectile entities do not visibly move in 1.16.100.04

1.16.100.04 has broken projectile spawning (visibly only.)

When spawning an entity, it visibly hovers at the initial spawn point instead of becoming an actual projectile. The projectile itself is actually invisible and does indeed travel the path it's supposed to.

This happens in single player and on BDS. The code to spawn the projectile remains unchanged in over 6 months, and was working perfectly until today:

"minecraft:projectile": {
        "on_hit": {
          "remove_on_hit": { },
          "particle_on_hit": {

            "on_other_hit": true
          },
          "impact_damage": {
              "damage": [
                1,
                4
              ],
              "knockback": false,
              "semi_random_diff_damage": false,
              "destroy_on_hit": true
          }
