Opening Backpack and Slimefun Guide at the same time causes unwanted behavior

[JustAHuman-xD]

❗ Checklist

• [X] I am using the official english version of Slimefun and did not modify the jar.
• [X] I am using an up to date "DEV" (not "RC") version of Slimefun.
• [X] I am aware that issues related to Slimefun addons need to be reported on their bug trackers and not here.
• [X] I searched for similar open issues and could not find an existing bug report on this.

📍 Description

(See reproduction steps and expected behavior) This bug can lead to mis use of the backpack, dupe bugs, etc. I have confirmed that this exists at least and I have been told that you can dupe items by allowing another player to upgrade the dropped backpack while you have it open, and then you both take out items.

📑 Reproduction Steps

1. Get a slimefun guide
2. Get a backpack
3. Place slimefun guide in off hand
4. Place backpack in main hand
5. Right Click to open inventory
6. Observe broken behavior (try moving the backpack item, putting disallowed items in the bag, etc)

(Note it works with the slots reversed, backpack in offhand guide in main) Observe that you can drop the backpack, put anything in the backpack, etc.

💡 Expected Behavior

I expect either the backpack to not open or if it does open to be properly recognized as a back pack and have all the correct handlers.

Afaik not related to other plugins

Can confirm if an outside source cancels either the PlayerInteractEvent or the PlayerRightClickEvent, it does not care and still fires both items. I've made a patch solution in a separate plugin that just closes the backpack when its dropped, idk how we'd fix this specifically

I'm starting to like backpacks less and less...

Reproductions steps are pretty unclear. If i right click in the inventory nothing happens.

By right click I mean right click to open the inventory, after that you can see the behavior, you can put the backpack in it self, you can drop the backpack on the floor you can do literally anything you are not supposed to be able to do.

This then seems fixed in the latest version i cant repro it

[JustAHuman-xD]

[JustAHuman-xD]

I can't reproduce it either

[JustAHuman-xD]

I'll try again after school using the latest paper builds and I'll let you know if it's still an issue

I guess I didn't update but when I did this I believe the issue still occurred, I'll check again shortly though

[JustAHuman-xD]

Yeah this is still an issue, atm on the latest paper 1.20.4, opening with either setup (bag in offhand or guide in offhand), the guide opens, then the bag opens, and all normal restrictions are gone. I can put other bags and shulker boxes and stuff in the bag, etc
