When saving with the cursor before a word, the first letter gets swallowed.

This project create by pnpm create vue@latest and add eslint-plugin-prettier.
And i remove pluginPrettier from eslint.config.ts, it can work, although it doesn't follow Prettier's formatting.

eslint.config.ts

import { globalIgnores } from 'eslint/config'
import { defineConfigWithVueTs, vueTsConfigs } from '@vue/eslint-config-typescript'
import pluginVue from 'eslint-plugin-vue'
import pluginVitest from '@vitest/eslint-plugin'
import pluginOxlint from 'eslint-plugin-oxlint'
import pluginPrettier from 'eslint-plugin-prettier/recommended'

export default defineConfigWithVueTs(
  {
    name: 'app/files-to-lint',
    files: ['**/*.{vue,ts,mts,tsx}'],
  },

  globalIgnores(['**/dist/**', '**/dist-ssr/**', '**/coverage/**']),

  ...pluginVue.configs['flat/essential'],
  vueTsConfigs.recommended,

  {
    ...pluginVitest.configs.recommended,
    files: ['src/**/__tests__/*'],
  },

  ...pluginOxlint.buildFromOxlintConfigFile('.oxlintrc.json'),

  // Just add this
  // After removing it, the issue of words being swallowed upon saving no longer occurs.
  pluginPrettier,
)

Reproduce the behavior using eslint.config.ts, .vscode/settings.json, and the listed package versions, with eslint-plugin-prettier enabled alongside oxlint and save-time fixes. Compare saving with the plugin enabled and removed; done means the first character remains intact while Prettier formatting still applies.
