Selecting Shulker Box of Bundles in inventory slows down the game

I'm not exactly sure how or why it happened, but I was just minding my own business when I started picking up shulker boxes to move stuff around. and the brown one that you can see in the video is full with bundles, and when i select it in my inventory my game started to slow down a lot, i tried grabbing other shulker boxes to see if the same would happen, but im pretty sure it only happens with bundles

How to Reproduce

• Fill shulker box with bundles

• open inventory

• select and move it around the screen
