Describe the bug

The NumberInput component incorrectly allows negative numbers despite setting the allowNegative attribute. When clicking the down arrow, it correctly reaches 0, but subsequent clicks result in the UI incrementing while the form value, managed by useForm, continues to decrement. I have tested this with both controlled and uncontrolled forms. I am not sure when this issue first started occurring, but I noticed it after upgrading to the latest version of both the core package and the forms package.
