<BooleanInput> - cannot set custom icons

[gartner]

In v3 I had customized to use specific icons/colors, like the manual says it should be done:

`import { BooleanInput } from 'react-admin';
import FavoriteIcon from '@mui/icons-material/Favorite';

<BooleanInput
source="favorite"
options={{
checkedIcon: ,
}}
/>`

It worked as expected in v3.

In v4, it does not work anymore.

Looking at the source of BooleanInput.tsx, it looks like the 'options' is not passed on to the underlying component. And that 'options' is removed by the call to sanitizeInputRestProps() ?
