Steps to reproduce

Create a Vue file with the following content:

<template>
    <div>
        {{ something }}
    </div>
</template>

<script lang="ts" setup>
defineProps({
    something: String,
});

defineModel();
</script>

What is expected?

The type of something should be string | undefined.

What is actually happening?

I am getting the following error:

Property 'something' does not exist on type 'CreateComponentPublicInstanceWithMixins<Readonly<__VLS_PublicProps & { "onUpdate:modelValue"?: ((modelValue: any) => any) | undefined; }>, {}, {}, {}, {}, ComponentOptionsMixin, ... 18 more ..., {}>'. ts-plugin(2339)

This also happens when I run vue-tsc.

Any additional comments?

It seems like there is a conflict between defineProps and defineModel.
