https://material-ui.com/components/text-fields/#multiline says

The multiline prop transforms the text field into a textarea or a TextareaAutosize.

It should mention when one or the other is chosen. Not hard to guess that if maxRows={4} is specified, it will return a TextArea, but what if I specify rows={4} as the initial size? Or if rows is omitted, what is the default?

Thanks!
