webpack 5 + Vue + TS-Loader how to use generics?

I tried to use generics with webpack and while I have no problems in my current Vite project I have no clue how to make it working with webpack.

I always receive TS2304: Cannot find name 'T'.
For example

<script setup lang="ts" generic="T extends string">
interface Props {
  modelValue: T;
}
const props = defineProps<Props>();
</script>

<template>{{ modelValue }}</template>

Is there a way to enable generics with this TS Loader and webpack 5? I created a minimal repo here
https://codesandbox.io/p/sandbox/webpack-vue-3-forked-p67wfr?welcome=true

Expected Behaviour

• Vue generics should work

Actual Behaviour

• Vue generics won't work -> see error above

Steps to Reproduce the Problem

• create a Vue component and try to use generics with webpack

Start with the linked CodeSandbox minimal repository and reproduce the TS2304 error using the shown Vue component and webpack 5 setup. Trace how ts-loader processes the component's generic script syntax and determine whether the issue is configuration or unsupported handling; done means the repository's expected generic usage works or the limitation is clearly documented.
