Weak vertical knockback in the component "minecraft:knockback_roar"

The “vertical_knockback” value of the “minecraft: knockback_roar” component is ignored, and apparently it takes a weak default one.

This is supposed to have been fixed in the beta “1.16.200.54”, but nothing has happened

How to replicate:

1. Download this behavior pack and put it in a world
2. In game, execute the command “/summon ex:knockback ~~~”
3. execute the command “/event entity @e[type=ex:knockback] explode”
