Steps to reproduce

vue create vue-cli-script-setup-lang-ts-typechecks -bi '{
      "useConfigFiles": false,
      "plugins": {
        "@vue/cli-plugin-typescript": {
          "classComponent": false
        }
      },
      "vueVersion": "3"
    }'
cd vue-cli-script-setup-lang-ts-typechecks

Add some wrongly typed code. E.g.:

echo '<script setup lang="ts">const x: string = 42;</script>' >> src/App.vue

Build

npm run build

What is expected?

The typescript error is detected and the build fails.

What is actually happening?

The typing is simply stripped and no error can be seen.
