Stuffing too many items into a bundle through commands will cause the capacity bar to overflow.

Steps to reproduce:

1. Use command:

   /give @s minecraft:bundle[minecraft:bundle_contents=[{count:99,id:"minecraft:shulker_box"}]]

2. Hover over the bundle

Expected behavior:
The capacity bar overflows.

What actually happened:
The capacity bar does not overflow.

Note:
The bundle in the attached picture is 99 diamonds with max_stack_size:1
