1.17and 1.17pre1 item dupe bug of craft table

1.17itemdupe bug

Summary:

Use mod itemscroller-fabric-1.17.0-0.15.0-dev.20210608.211652 and malilib-fabric-1.17.0-0.10.0-dev.22+beta.1 crafting some Items may be copied or lost in large numbers on crafting_table.

Expectation:

The number of products item should be the same as the number of materials item that can be synthesized.

In practice:

1.When use that mod and craft on craft_table so quickly,the item number of crafting grid may become soooooooooo large.Sounds like my game screenshots.And these unusual items can be thrown out,Others server players can see it and pick it up.They were supposed to be ghost items(like 1.15,they are normal).
In fact, composite items are sometimes lost and sometimes dupe.

One more thing:

We've observed a few item that they can never be picked up,that means player can pick up an infinite number of items.
A player's screenshot shows an entity has 90 items
Besides,I've seen similar bugs in previous snapshoot versions but in1.17 and 1.17pre1 I still found the bug,what do u do mojang

The attachment

Two of the mods that I used,game screenshot and item dupe video.
In testing, the bug appeared in both of 1.17 and 1.17pre1 server and single-player versions of the game.
