False positive TS1323 error about static imports in <script setup lang="ts">

[micgro42]

When in tsconfig.json the "module" compiler option is set to es2015, then vue-tsc produces an error for static imports inside <script setup lang="ts">

For example for this code straight from the vite scaffold:

<script setup lang="ts">
// This starter template is using Vue 3 <script setup> SFCs
// Check out https://vuejs.org/api/sfc-script-setup.html#script-setup
import HelloWorld from './components/HelloWorld.vue'
</script>

This is the error message that is produced:

src/App.vue:1:1 - error TS1323: Dynamic imports are only supported when the '--module' flag is set to 'es2020', 'es2022', 'esnext', 'commonjs', 'amd', 'system', 'umd', 'node12', or 'nodenext'.

As you can see, there is no dynamic import in App.vue, only a static one.

I create a minimal failing example repository for this, reproducing the error on npm run build: https://github.com/micgro42/Minimal-Failing-Example_volar-dynamic-import

It is the repository produced by npm create vite@latest and the tsconfig.json modified as stated above.

As far as I can tell, this started with vue-tsc 0.34.x. That is, it was working fine with 0.33.9 and broke when we tried to upgrade to 0.34.11.

Please let me know if you need any further information.
