Vue version

3.3.2

Link to minimal reproduction

vuetifyjs/vuetify#16190

Steps to reproduce

Build a library with

DefineComponent<MyProps, {}, {}, {}, {}, {}, {}, {}, {}, VNodeProps & AllowedComponentProps & ComponentCustomProps>

What is expected?

The emitted type includes

$props: MyProps & vue.VNodeProps & vue.AllowedComponentProps & vue.ComponentCustomProps

Consumers of the library can use module augmentation to set ComponentCustomProps

What is actually happening?

Prettify added in 4c9bfd2 flattens it to

$props: { foo?: string, bar?: string }

Consumers cannot add anything with ComponentCustomProps
