The Bug:

When a player packs or unpacks items (within the inventory) using bundles, "minecraft.used:minecraft.bundle" doesn't increase.

Please note that this scoreboard objective correctly increases when items are emptied from bundles (outside of the inventory).

Steps to Reproduce:

1. Create a scoreboard objective for tracking when you use a bundle and set it to display on the sidebar by using the commands provided below.

   /scoreboard objectives add UseBundle minecraft.used:minecraft.bundle

   /scoreboard objectives setdisplay sidebar UseBundle

2. Obtain a bundle along with some items by using the commands provided below.

   /give @s minecraft:bundle

   /give @s minecraft:dirt 64

3. Pack and unpack items (within the inventory) several times using the bundle.
4. Take note as to whether or not "minecraft.used:minecraft.bundle" increases when packing or unpacking items using bundles.

Observed Behavior:

The scoreboard doesn't increase.

Expected Behavior:

The scoreboard would increase as the bundle is being used to pack/unpack items.
