Item/block display entities don't render correctly behind item/block display with transparent textures when scaling to big sizes

Hello, I was trying to make a custom mob using the new display entities. My problem is that when I scale my item display entity to big sizes (the red transparent circle in this video: https://www.youtube.com/watch?v=J7_5dyyfSPA), the Item/Block display behind doesn't render correctly depending of the point of view of the player.

Commands used in the screenshots : 

/summon item_display ~ ~ ~ {item:{id:"minecraft:ice",Count:1b}}

/data merge entity @e[type=item_display,limit=1,sort=nearest] 

{interpolation_duration:200,transformation:\{scale:[3f,200f,200f]}

}
