Passing styled-components <Input /> into Select throws warning

[donovanhiland]

I'm trying to pass an Input component styled with styled-components into select and getting the warning:
Material-UI: you have provided an invalid value to the inputproperty., We expect an element instance of theInput component.

• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

I should be able to pass an Input styled with styled components to Select

const StyledInput = styled(Input)
<Select input={<StyledInput />} />

Current Behavior

Throws warning:

warning(
  isMuiElement(input, ['Input']),
  [
    'Material-UI: you have provided an invalid value to the `input` property.',
    'We expect an element instance of the `Input` component.',
  ].join('\n'),
);

You are missing this line StyledInput.muiName = 'Input'.

We need to improve the documentation.
