The title attribute is not working correctly on the checkbox, when the mouse is on the area serrounding the checkbox it works but not when the mouse is on the input element.
This is my checkbox code:
const StyledCheckbox = withStyles({
colorPrimary: {
    borderColor: '#757575',
    borderRadius: 1,
    '&$checked': {
        color: '#00adb3'
    },
},
checked: {},})(Checkbox);
and the render
 public render() {
    return <>
        <div className='checkbox-react'>
            <StyledCheckbox  color='primary' checked={this.state.checked} onClick={this.handleChange}
                                     title={'test test'}  onChange={this.handleChange}   />
        </div>
    </>;
}
