[autocomplete] Regression with 7.3 and Playwright

[tux21b]

Steps to reproduce

Steps:

1. Create a MUI AutoComplete with freeSolo={true}
2. Use Playwright to .fill("foobar") and .press("Enter")

Current behavior

Starting with Material UI 7.3 onChange is called with [undefined] when run within Playwright. I wasn't able to reproduce the behavior when interacting manually with the Autocomplete field.

Expected behavior

onChange should be called with ["foobar"] like in Material UI 7.2.

@tux21b Would you mind providing a minimal repro?

Comparing v7.2.0 against v7.3.0, I don't see any changes to Autocomplete other than 472cc72#diff-a3e15b1f22a8ed2de23c8cee46ea92a1d2828d4718cb471c6404d9baadd2c68f

We're seeing the same behavior in our app with MUI v7.3+ without Playwright. Downgrading to v7.2.0 fixed the issue. I will try to create a reproduction repo

[olivier-lxo]

I was able to reproduce it here: https://stackblitz.com/edit/zl8qpkqz?file=src%2FDemo.tsx,package.json

To reproduce: enter any text in the text field and blur out of the field. The value should be whatever text you entered but will stay undefined.

The behavior is triggered when the options array is empty and autoHighlight is set to true.

The bug was introduced with v7.3.0. Downgrading to v7.2.0 fixes it.

Thanks for posting a reproducable example and for letting me know that I am not the only one who can not use MUI >=7.3 because of regressions.

I am not sure why the bot has immediatelly closed the issue again, lets hope a reply will change its mind.
