This is not required as ts will infer type of values as

{
  textmask: string;
  numberformat: string;
}

Side note. It makes me think that we could replace

    <Box
      sx={{
        '& > :not(style)': {
          m: 1,
        },
      }}
    >

with the <Stack> now that the component exists.

sx={{
        '& > :not(style)': {
          m: 1,
        },
      }}

Total 3 demos have this selector, so maybe it's better to do all of them at once in single PR
