The game now crashes when viewing the tooltip of a bundle containing an item stack with incompatible data

This behavior was introduced in 26.1-snapshot-3.

The bug

When viewing the tooltip of a bundle containing an item stack with incompatible data, the game tends to render an empty item stack, causing it to crash with the following error:

The game crashed: rendering screen
Error: java.lang.IllegalStateException: Stack must be non-empty

Steps to reproduce

1. Create an item stack with incompatible data and put it into a bundle, or create a bundle containing an item stack with incompatible data. This can be done …

   • … with an item stack that has a max_stack_item value different from 1 and also has the max_damage component.
     
     One way to obtain such an item is to use the following command above a chest containing an item with the max_damage component.

     data modify block ~ ~-1 ~ Items[0].components merge value {"minecraft:max_stack_size":99}

     data modify block ~ ~-1 ~ Items[0].components merge value {"minecraft:max_stack_size":99}

   • … with an item stack that has a count greater than the max_stack_item component.
     
     One way to obtain such a bundle is to use the following command above a chest containing a bundle with an item with the max_stack_item component less than value.

     data modify block ~ ~-1 ~ Items[0].components."minecraft:bundle_contents"[0].count set value <value>

     data modify block ~ ~-1 ~ Items[0].components."minecraft:bundle_contents"[0].count set value <value>

2. Hover the mouse cursor over the bundle.

Additional notes

The attached video shows some OBS Studio freezes and a cut between the first crash and opening the world again; neither corresponds to a bug in the game.
