As title.

There is a 2 gt delay between applying attribute modifiers to items and the attribute modifiers actually taking effect.
Modifiers applied by command /attribute are not affected.

The attachment is a datapack including some functions to verify the bug.

Steps to reproduce

1. install the datapack and reload
2. run /function test:direct/modify_attribute to see values queried by /attribute with modifiers applied by /attribute
3. run /function test:item/modify_attribute to see values queried by /attribute with modifiers applied on item by /item and item modifier file

Note

• all selectors in the datapack are @p in order to simplify the code
• modifier is automatically removed after 3 gt
