Wind charge hitbox is larger than visually displayed

If you spawn a wind charge, its hitbox size will be larger then visually displayed with hitboxes (open with f3+b)
Steps to reproduce:
1: (for wind charge) Type the command /summon minecraft:wind_charge ~ ~2 ~
2: Turn on hitboxes with f3+b
3: Hit the air near where but not on the hitbox
4: The wind charge will move/explode

I have linked a video here: https://youtu.be/4I9gpU7KsFA (Note: This video is from before I knew that you didn't need heaps of wind charges stacked up on each other, a single one works fine
Also the hitbox size is similar to an end crystal
