[oliviertassinari]

Steps to reproduce

Link to live example: (required)

Steps:

1. Open https://mui.com/material-ui/material-icons/?query=alert

https://github.com/mui/material-ui/assets/3165635/ff4f006e-9268-4365-8d4a-05aa2d97a60e

Current behavior

Main thread blocked

Expected behavior

No massive chunk of blocked time

Context

Google is aware of this problem, Chrome is feeding it back data about the page, see ahref INP data fetched from Google. Same data in https://pagespeed.web.dev/analysis/https-mui-com-material-ui-material-icons/253fjl9n29?form_factor=desktop

Horrible:

I would imagine that https://react.dev/reference/react/useTransition is the solution

Your environment

npx @mui/envinfo

``` Don't forget to mention which browser you used. Output from `npx @mui/envinfo` goes here. ```
