Steps to reproduce

In my vscode, create a vue typescript project , pnpm create vite && pnpm i
then copy the code from above playground , I cannot see type declaration on click when I mouse on it

What is expected?

export default defineComponent({
  emits: {
    /** fired on clicked */
    click(data: number, ev: MouseEvent) {
      return true;
    }
  }
...............
}

will generate the demo.d.ts as below

Readonly<import('vue').ExtractPropTypes<{
    /** simple prop */
    type: {
        type: StringConstructor;
    };
    /** event as prop */
    onChange: {
        type: FunctionConstructor;
    };
}>> & {
    onClick?: ((data: number, ev: MouseEvent) => any) | undefined;
},

I expect that before onClick line , it comes with type declaration------/** fired on clicked */

What is actually happening?

As in the screenshot, the is no intellisense on click

I think it's easy to fix. I'm locating the problem below:
(

core/packages/runtime-core/src/componentEmits.ts

Line 40 in 0b8ba63

export type EmitsToProps<T extends EmitsOptions> = T extends string[]

)
