Attribute modifiers don't reset after death 1.21.1

Expected behavior

1. the player have an attribute ( like this one for exemple : /attribute @p minecraft:generic.max_health modifier add 1 10 add_value
2. the player died
3. the attribute is reset because in this case, the attribute is not the Base attribute

here an exemple of vanilla 1.21.1

Reproduce the issue on Paper 1.21.1 using the /attribute command, then kill the player in survival mode and inspect whether the generic.max_health modifier remains active.
