Logs

Start with the Nuxt ^3.6.5 reproduction using nuxt.config.ts: enable devtools, run npm run dev, remove the setting, and restart the server. Compare whether devtools remains in the browser and whether the application becomes unresponsive. Done means removing the configuration also removes devtools and the application remains responsive.
