Code

import { Select } from '@material-ui/core';

import React from 'react';

export function Repro({ SelectProps = {} }: { SelectProps?: Partial<React.ComponentProps<typeof Select>> }) {
    return (
        <Select value={'test'} {...SelectProps} />
    );
}

Expected behavior:
No error, as value in SelectProps is optional and SelectProps even defaults to an empty object.

Actual behavior:

'value' is specified more than once, so this usage will be overwritten.ts(2783)
Repro.tsx(7, 32): This spread always overwrites this property.

Playground Link:
none, as the playground does not seem to load the material-ui types

I noticed that this issue has 4.0 as milestone.
If 4.0 will have breaking changes and this bug was introduced in 3.9.2, it might be worth to consider making a fix for this bug in 3.9.x?

Same problem with

   "@material-ui/core": "4.9.14",
   "typescript": "3.9.2",

Reverting typescript to
"typescript": "3.8.3",
solves the problem.
