Enchantment effect `attribute` for `minecraft:max_health` resets to 20 health on world join.

Unlike a normal /attribute command modifier or minecraft:health_boost status effect, minecraft:attributes enchantment effect for minecraft:max_health attribute does NOT maintain the player’s health value above 20 when they rejoin the world, meaning they have to spend saturation/food to regenerate the missing health they had before leaving the world.

Example enchantment test:extra_health:

{
    "description": {
        "translate": "HESOYAM"
    },
    "supported_items": "minecraft:leather_chestplate",
    "weight": 1,
    "max_level": 1,
    "min_cost": {
        "base": 0,
        "per_level_above_first": 0
    },
    "max_cost": {
        "base": 0,
        "per_level_above_first": 0
    },
    "anvil_cost": 0,
    "slots": [
        "chest"
    ],
    "effects": {
        "minecraft:attributes": [
            {
                "attribute": "minecraft:max_health",
                "id": "test:enchantment.extra_health",
                "amount": 10,
                "operation": "add_value"
            }
        ]
    }
}

This bug/inconsistency starts all the way from 1.21 and up.
