Using a vanilla item as an icon breaks custom groups.

When creating a custom group with a vanilla item as the icon using the new "minecraft:crafting_items_catalog" breaks the custom group.

Steps to reproduce:

• Download the add-on attached

• Launch Preview 1.21.60.24

• Open Creative Menu -> Navigate to Nature tab

• Notice there is two new custom groups near the bottom

mojira:itemGroup.name.custom_group

mojira:itemGroup.name.custom_group_two

• Try opening both groups

Expected Behaviour:

Opening mojira:itemGroup.name.custom_group will expand the custom group.

Opening mojira:itemGroup.name.custom_group_two will expand the custom group.

Actual Behaviour:

Opening mojira:itemGroup.name.custom_group does not expand the group. Rather, the vanilla item being used as the icon gains the +/- symbol.

Opening mojira:itemGroup.name.custom_group_two expands the custom group.
