Putting items in a bundle in creative can cause a desync making the bundle item flash

When putting an item into a bundle and/or quickly picking up the bundle at the same time, the bundle can desync, causing erratic and violent flashing for the item.

Steps to Reproduce:

1. Get a bundle
2. Get a single stack item
3. Pick up the single stack item in your cursor
4. (Hovering over the bundle item with it) spam click right and left mouse button

Expected Result:

Either the item would be put in/taken out, or the bundle would be picked up/put down into the slot.

Observed Behavior:

The inventory slot flashes repeatedly between a full bundle and/or an empty bundle and/or the item you inserted.
