      The bug

      When you summon a mob only with a given value for the generic.maxHealth attribute the value for the Health tag is the default health value of this mob which can be higher than the value of the attribute generic.maxHealth. If you however provide the Health tag, the attribute value is used as maximum value.

      How to reproduce

      1. Use the following command
        /summon Wolf ~ ~ ~ {Attributes:[{Name:"generic.maxHealth",Base:0.1d}]}
      2. Inspect the NBT data, you will see that its Health value is the default 8f
      3. Use the following code
        Health provided
        /summon Wolf ~ ~ ~ {Attributes:[{Name:"generic.maxHealth",Base:0.1d}],Health:8f}
      4. Inspect the NBT data, you will see that its Health value is now the value of the generic.maxHealth attribute.

      Wrong maxHealth value is used

      Based on Skylinerw's comment on MC-93830 it also appears that the game is not using the value for the generic.maxHealth attribute the mob has at the end.

      The following command will cause Health to be set to the maximum value defined by the generic.maxHealth attribute in the command, however the game overrides this value with the default 20d. This means the Health value of 2f would have been valid.

      /summon Wolf ~ ~1 ~ {OwnerUUID:"00000000-0000-0000-0000-000000000000",Attributes:[{Name:"generic.maxHealth",Base:0.1d}],Health:2f}
