The block component "minecraft:transformation" does not avoid the block being beyond its scale and translation limits if a geometry is being used. This means that something like:

"minecraft:transformation": {
                        "scale": [64, 64, 64],
                        "translation": [64, 64, 64]
}

Will work, causing the geometry to be upscaled to any possible amount. The scale parameter should keep the same limits the geometry has which are 30/16.
I have attached a pack to reproduce this bug. Here are the steps to reproduce:

1. Download the attached .mcaddon file.
2. Create a new world with HCF toggle on.
3. Apply both RP and BP.
4. Join the world
5. Type in chat;

/give @s kai:

and three of the blocks in the pack will appear, give yourself all of them.
6. Place the blocks with a reasonable distance between each and step back.

After doing these steps, the bug will appear by itself.
