package.json dependencies

"dependencies": { "vue": "^3.5.12" }, "devDependencies": { "@tsconfig/node20": "^20.1.4", "@types/node": "^20.16.11", "@vitejs/plugin-vue": "^5.1.4", "@vue/tsconfig": "^0.5.1", "npm-run-all2": "^6.2.3", "typescript": "~5.5.4", "vite": "^5.4.8", "vue-tsc": "^2.1.6" }

Steps to reproduce

1. Create a simple Vue project using npm create vue@latest.
2. Create a child component named CompA.
3. Create another child component named CompB.
4. Import both components into App.vue.
5. Use CompA in App.vue with a v-for directive.
6. Use CompB after CompA and ensure it can be folded.
7. Create a div element after CompB with an arbitrary class name.
8. Fold CompB to observe the issue.

Here is a sample repository volar-issue-highlighting-loss that has already been created for this issue.

Below is the content of the component app.vue.

<template> <comp-a v-for="(cell, ind) in new Array()" :key="ind"></comp-a> <comp-a></comp-a> <comp-a></comp-a> <comp-b></comp-b> <comp-b></comp-b> <comp-b></comp-b> <comp-b> <div>ccc</div> </comp-b> <div class="xxx">ddd</div> </template> <script setup lang="ts"> import CompA from "./CompA.vue"; import CompB from "./CompB.vue"; </script> 

What is expected?

When the "comp-b" component is folded, the "comp-a" component is highlighted in green.

This screenshot shows the effect when using volar@v1.8.27.

What is actually happening?

When the "comp-b" component is folded, the "comp-a" component loses its highlight display.

This screenshot shows the effect when using volar@v2.1.6.
