MuiButtonBase-root override MuiButton-root

I have a component where I override Button root class, but ButtonBaseRoot is overriding my styles.

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

Current Behavior 😯

ButtonBaseRoot style is overriding Button given classes.

Expected Behavior 🤔

Classes given to Button should override all button styles

Steps to Reproduce 🕹

    import { Button } from '@material-ui/core';
    import { makeStyles } from '@material-ui/styles';
    import React from 'react';

    const useStyles = makeStyles({ root: { backgroundColor: 'red' } });

    const MyButton = (props) => {
        const classes = useStyles();
    
        return <Button classes={classes} {...props} />;
    }

I’m still with this problem after upgrading to mUI 5, but the weird thing is that it happens only in some pages, not all.

Anyone found a solution?

Noticed the error with @mui/material 5.1.0 as well.
