Bug: Formatting resets some content of a file

[dominicmeyer]

Problem

On some files, neovim seems to get 'stuck' on some values and when doing vim.lsp.buf.format({ async = false }) the changes get undone.

The above is an example from my current vue project. The content after using the command is the previous content of those fields. Right now I observed it happening with volar, but I'm not sure, if this is caused by volar or Lsp-Zero.

When doing the command this happens:

<template>
	<div class="d-flex align-center justify-center pa-4">
		<v-btn :disabled="page === 1" icon="mdi-arrow-left" density="comfortable" variant="tonal" rounded
-			@click="emit('prevPage')"></v-btn>
+                       @click="prevPage"></v-btn>

		<div class="mx-2 text-caption">
			Page {{ page }} of {{ pageCount }}
		</div>

		<v-btn :disabled="page >= pageCount" icon="mdi-arrow-right" density="comfortable" variant="tonal" rounded
-			@click="emit('nextPage')"></v-btn>
+                       @click="nextPage"></v-btn>
	</div>
</template>

<script setup lang="ts">
import { defineProps } from 'vue';

defineEmits(["nextPage", "prevPage"])

defineProps({
  page: {
	  type: Number,
		required: true
	},
  pageCount: {
	  type: Number,
		required: true
	},
  nextPage: {
		type: Function,
		required: true
	},
  prevPage: {
		type: Function,
		required: true
	}
})
</script>

Steps to reproduce

Still unknown, seems the happening random.

Expected behavior

Refactoring not changing the codes content like this

Neovim version

0.9.2

Lsp-Zero config (Lazy.nvim)

return {
	{
		'williamboman/mason.nvim',
		version = "1.8.3"
	},
	{
		'williamboman/mason-lspconfig.nvim',
		version = "v1.22.0"
	},
	{
		'VonHeikemen/lsp-zero.nvim',
		branch = 'v3.x'
	},
	{
		'neovim/nvim-lspconfig',
		commit = "29939f6f07bc0f3b9fc563fbfbee06ac88c8c439"

		commit = "44b16d11215dce86f253ce0c30949813c0a90765"
	},
	{

		version = "v0.0.1"
	},
	{
		'L3MON4D3/LuaSnip',
		version = "v2.1.0"
	}
}

local lsp_zero = require('lsp-zero')
lsp_zero.extend_lspconfig()

lsp_zero.on_attach(function(client, bufnr)
	-- see :help lsp-zero-keybindings
	-- to learn the available actions
	lsp_zero.default_keymaps({ buffer = bufnr })
end)

require('mason').setup({})
require('mason-lspconfig').setup({
	ensure_installed = { "dockerls", "bashls", "volar", "yamlls", "jsonls", "pylsp",
		"marksman", "rust_analyzer", "tsserver", "emmet_ls", "html", "lua_ls" },
	handlers = {
		lsp_zero.default_setup,
	},
})
