      The bug

      When I give myself extra max health with an attribute, then gain health, log out and log back in there are empty hearts but not the health.

      Steps to Reproduce:

      • Give yourself a diamond sword that grants double health and hold it in your main hand.
      • /give @s minecraft:diamond_sword{AttributeModifiers:[{AttributeName:"minecraft:generic.max_health",Amount:20,UUID:[I;1,2,3,4],Slot:"mainhand"}]}
      • Give yourself some regeneration.
      • /effect give @s minecraft:regeneration 3 3 false
      • Take note of the health you currently have.
      • Reload into the world and once again, take note of the health that you now have.

      Observed Behavior:
      Additional health granted with items that have attributes is lost upon reloading the world.

      Expected Behavior:
      Additional health granted with items that have attributes would not be lost upon reloading the world.
