Material-ui: [Select] can't disable underline with inputProps

[otalrecall]

• [x] The issue is present in the latest release.
• [x] I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

I can't pass the prop 'disableUnderline' to the Input component inside Select. It returns a warning 'React does not recognize the disableUnderline prop on a DOM element'.

Expected Behavior 🤔

I assume it should be possible to override the styling of the underline class in Input when using the Select component, but currently it doesn't work this way.

Steps to Reproduce 🕹

<Select inputProps={{ disableUnderline: true }}></Select>

1. Open codesandbox example
2. Check the Input underline is still visible even though the prop disableUnderline is passed.

<Select disableUnderline>

This worked for me. Strange this is that the inputProps as described in Select API documentation - https://material-ui.com/api/select/, is supposed to pass the property to underlying input component. Document on https://material-ui.com/api/input/ acknowledges the use of this property.
