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.
