Block hitboxes and entity hitboxes don’t render behind semi-transparent entities

Selected block and entity hitboxes are not rendered behind semi-transparent entites, such as the player in spectator mode, or when on a team with invisibility applied.

Steps to Reproduce:

^{(Fabulous! graphics must be enabled)}

1. Add a team and join it

   /team add hitbox_invisible
   /team join hitbox_invisible@s

2. Apply invisibility OR enter spectator mode

   /effect give @s minecraft:invisibility infinite 0 true

3. Enter the third-person perspective

4. Look directly at a block, or an entity with hitboxes enabled (F3 + B)
   → ❌ The hitbox is not rendered properly

Notes:

1. This occurs even when the 'Fabulous!' setting is enabled

2. When 'Fabulous!' graphics is disabled, the entity will not render at all, that behavior is tracked in MC-187783
