In the item generator for resource packs, there is a component called "creative_slot_lock". This is only ever used in-game for the papers in the Saved Hotbars menu and is impossible to get in any other way as far as I'm aware (commands can't give you an item with it either). I tried modifying the texture of said papers and it didn't recognize the component. I have come to the conclusion that creative_slot_lock is simply not able to be detected by resource packs. Because of this, unless anyone can figure out how to make it work, it should be removed from the item generator.
For context, I did this in 26.2 with the item generator also set to 26.2.
