camelCase prop names not converting to kebab-case when using defineComponent with function signature

[CernyMatej]

Vue version

3.4.21

https://stackblitz.com/edit/vitejs-vite-uxfxn6?file=src%2FApp.vue,package.json&terminal=dev

Steps to reproduce

When defining a component using defineComponent with the new function signature, prop types are not generated with kebab-case names. This results in a type error when using the component in the template with kebab-case props.

Steps to reproduce:

1. Open the reproduction.
2. Run vue-tsc in the terminal.

What is expected?

No type error should be raised when the component props in the template are defined using kebab-case.

What is actually happening?

An error is being raised:

src/App.vue:38:6 - error TS2345: Argument of type '{ "aria-label": string; }' is not assignable to parameter of type '{ ariaLabel: string; } & VNodeProps & AllowedComponentProps & ComponentCustomProps & Record<string, unknown>'.
  Property 'ariaLabel' is missing in type '{ "aria-label": string; }' but required in type '{ ariaLabel: string; }'.

Didn't realize it was a problem with only aria- attributes. Linking vuejs/language-tools#4219 then... 👍
