Formatting issue on 0.40.8 and 0.40.9

[sevillaarvin]

Hello, I'm using @volar/vue-language-server with emacs/eglot and I encounted a bug with the textDocument/formatting method.

I have a simple test.vue page with bare bones tags. When I request a format, the server's reply removes essential characters that have no syntax errors.

This happens only in 0.40.8 and 0.40.9, not in 0.40.7.

Any advice is appreciated, thanks!

test.vue before format

<script setup>
asdf
</script>

<template>
</template>

<style scoped>
</style>

test.vue after format

<script setup>
asdf
t >

  <template>
e>

    <style scoped>
    </style>
