Current behavior 😯

Expected behavior 🤔

Context 🔦

This is a regression in behavior from Material UI, e.g. https://mui.com/material-ui/react-select/#basic-select, which we would need to fix for Material UI v6 to depend on Base UI.

I noticed this on the https://github.com/mui/material-ui/tree/master/examples/base-next-app-router-tailwind-ts which feels broken:

Joy UI is broken too.
