Describe the bug

Hi 👋 , strange issue happening only with lang="ts". at line 30 in page/index.vue the export default is considered as part of the component code. It triggers a multiple default warning during static generation.

Current workaround is to avoid typescript by removing lang="ts"

this might be an upstream issue ?
