The potion effect background sprite isn’t 9-sliced, unlike the item tooltip background, resulting in effect name going past the background, or just having empty space..
How to replicate bug:
Go in a world or make a new one
Type /effect give @s minecraft:hero_of_the_village
Open the Inventory
Expected result:
The text would appear inside the background
What actually happened:
The text goes past the background
