shadcn FancySelect breaks on multiple items with the same label

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

shadcn

Version

6.4.1

Current Behavior

FancySelectItem has value and label. While certainly not ideal, you can have two items with the same label but different values (IDs). This breaks the UI, since the value is not passed on to CommandItem.

The cmdk docs state:

You should provide a unique value for each item, but it will be automatically inferred from the .textContent.

Expected Behavior

The FancySelect widget should be able to handle multiple items with the same label but different values.

Steps To Reproduce

Something like this, but the shadcn CSS setup is missing: https://codesandbox.io/p/sandbox/vjpy43

You can see it in the rendered HTML though, both items have data-selected="true".
