Some items with empty attribute list receive additional data after interacting with them in the inventory

[Toseflo]

Expected behavior

Moving an item in an inventory shouldn't change the item data

Observed/Actual behavior

Moving a shield with attribute_modifiers:{show_in_tooltip: 0b, modifiers:[]} adds banner_patterns:[] to the item components

Steps/models to reproduce

As requested in this bug report (https://github.com/PaperMC/Paper/issues/10686), here is the new bug report for the shield issue.

1. Give yourself a custom shield with /give @p minecraft:shield[minecraft:attribute_modifiers={show_in_tooltip:0b,modifiers:[]}]
2. Use /data get entity @s SelectedItem to confirm that the shield just has this component
3. Pick this item up with your cursor and place it in the inventory again
4. Use /data get entity @s SelectedItem again and notice how the shield now also has the component banner_patterns:[]
