Multiline TextField scrollbar does not work when used with 'unit' prop

[AndreasPresthammer]

The scrollbar in the TextField component does not work when multiline and unit props are enabled.

See repro in codesandbox: https://codesandbox.io/p/sandbox/react-18-playground-forked-fts4gc?file=%2Fsrc%2FApp.tsx%3A23%2C29

Expected behavior

Expect that you can drag the scrollbar to scroll. NB! The scroll buttons up and down still work, and the scroll wheel also work.
