Current behavior 😯

When having a multiline textfield inside autocomplete, it logs an error (only in non-production):

MUI: Unable to find the input element. It was resolved to [object HTMLTextAreaElement] while an HTMLInputElement was expected.
Instead, Autocomplete expects an input element.

Make sure you have customized the input component correctly. 

However aside the error log, it works as expected.

Expected behavior 🤔

Having a multiline textfield inside autocomplete, should not log an error.

Steps to reproduce 🕹

1. Have a multiline textfield inside renderInput of autocomplete

Context 🔦

I need to have a autocomplete with a textfield that supports multiline. The error seems to come from this check, however I don’t really get why a Textarea is not supported.

There’s no way to remove it in dev mode. It doesn’t show up in the production build.
