Upgrading to @mui/material ^5.10.11 the styling isn't working with TextFieldsProps `size: small` option

[Fedu]

In case you're upgrading to @mui/material ^5.10.11 and you're using the TextFieldProps={{ size: 'small' }} ie.

<MuiOtpInput
  TextFieldsProps={{ size: 'small', placeholder: '-' }}
  length={6}
  validateChar={validateChar}
  value={otp}
  onChange={setOtp}
  onComplete={onOtpComplete}
/>

It might look something like this:

Here's one possible HOTFIX. Add this to your globals.css or similar:

.MuiInputBase-sizeSmall {
  min-width: 2rem !important;
}

For me, it fixed the issue.
