The Issue:

Players who can't effectively use a scroll wheel using keyboard and mouse controls without full keyboard gameplay (whether due to player disability or just broken/missing hardware) are able to remove only the very "topmost"/newly added item from a bundle, while players who are able to use a working scroll wheel or possibly other platforms may choose freely from the topmost 8-12 items of a bundle. This is also related to MC-276968

What I expected to happen was:

Controls using keyboard and mouse controls for cycling through items without full keyboard gameplay would be remappable, like nearly all other controls, through the Settings > Controls - Keyboard & Mouse menu.

What actually happened was:

For those who use a keyboard and mouse without full keyboard gameplay, some people can remove only the very topmost item from a bundle, making bundles much less useful than they are to other players.

Steps to Reproduce:

1. Try playing with any of the following conditions. Some conditions are required to be met:

• Usage of keyboard and mouse with either no scroll wheel or a broken scroll wheel - Required
• A mouse with no scroll wheel - Option 1
• A mouse with a broken scroll wheel - Option 2
• Not using the "Full Keyboard Gameplay" Option - Likely required

If you cannot meet all those required conditions, there might have to be someone else needed to reproduce this issue.

2. Get a bundle

3. Put at least 2 different types of items into a bundle.

4. For those who use a keyboard, a mouse with either a broken or no scroll wheel and without full keyboard gameplay, they can only take out the topmost item out of the bundle. You can't also try to take items out of a bundle which are not the topmost item using the number keys.
