Steps to reproduce

In a .vue file with a javascript block comment directly before export default, the comment can not be folded/collapsed in vscode. It make no difference if it's a <script>, <script lang="ts"> or <script lang="js"> tag

The below code will not fold (or offer the arrow to collapse when hovering the line):

<script lang="ts">
/**
 * @name 
 * @description 
 */
export default defineComponent({

});
</script>

However, if you add a line of js code between the comment and the export, the comment will fold as expected (and offer the arrow when hovering over the line):

<script lang="ts">
/**
 * @name 
 * @description 
 */
const a = "";
export default defineComponent({

});
</script>
