Bug: Cannot redefine property: nodeName when beasties is added

[EmmaKnijn]

I am trying to use beasties in my project, and it is failing to build the server ssg environment when I run npm run build. The moment that I remove beasties the build goes through fine

vite.config.js:

import { fileURLToPath, URL } from 'node:url'
import { beasties } from 'vite-plugin-beasties'
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import vueDevTools from 'vite-plugin-vue-devtools'

// https://vite.dev/config/
export default defineConfig({
  plugins: [
    vue(),
    vueDevTools(),

    beasties({
      // Plugin options
      options: {
        // Beasties library options
        inlineThreshold: 4000, // Inline stylesheets smaller than 4kb
      },
    }),
  ],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url))
    },
  },
  build: {
    // Generate static assets in the dist directory
    outDir: 'dist',
    // Ensure all assets are included in the build
    assetsInlineLimit: 0,
    // Optimize the build for production
    minify: 'terser',
    // Generate source maps for debugging
    sourcemap: false,
    // Configure rollup options
    rollupOptions: {
      output: {
        // Ensure assets are properly named
        entryFileNames: 'assets/[name].[hash].js',
        chunkFileNames: 'assets/[name].[hash].js',
        assetFileNames: 'assets/[name].[hash].[ext]'
      }
    }
  },
  server: {allowedHosts: true}
})
