Placeholder load different size of image and different place

See original GitHub issue

Hi, Blue I am using SimpleImg, but when I wanna load an image with a specific size, it loads the placeholder in a different place with a different size. This is the wrapper.

import React from 'react';
import PropTypes from 'prop-types';
import { SimpleImg, SimpleImgProvider } from 'react-simple-img';

const LazyLoadingImage = React.memo(function LazyLoadingImage(props){
    const { threshold, img, imgPlaceHolder, duration, height, width } = props;
    return (
        <SimpleImgProvider
            config={{ threshold: [threshold || 0.5] }}
        >
            <SimpleImg
                height={height || 500}
                width={width || 500}
                sizes={
                    `(max-width: ${width || 500}px)
                     (max-height: ${height || 500}px)
                    `
                }
                duration={duration || 2}
                placeholder={imgPlaceHolder}
                src={img}
            />
        </SimpleImgProvider>
    );
});

LazyLoadingImage.propTypes = {
    img: PropTypes.object.isRequired,
    imgPlaceHolder: PropTypes.object.isRequired,
};

export default LazyLoadingImage;

And usage

import React, { lazy, Suspense } from 'react';
import ebook from '../../imgs/e-book.png';
import ebookplaceholder from '../../imgs/e-book-placeholder-8.png';
import DivFlex from '../styled/DivFlex';
import logo2 from '../../imgs/Logo2.png';
import logo2placeholder from '../../imgs/logo2-placeholder-8.png';

const LazyLoadingImage = lazy(() => import(/* webpackChunkName: "LazyLoadingImage" */ 
    '../Shared/LazyLoadingImage'));

const MiddleEbook = () => {
    return (
        <Suspense fallback={<div> Loadding ...</div>}>
            <DivFlex style={{ marginTop: '15rem', border: '1px solid red'}}>
                <LazyLoadingImage img={ebook} imgPlaceHolder={ebookplaceholder} />
                <DivFlex>
                    <LazyLoadingImage img={logo2} imgPlaceHolder={logo2placeholder} 
                        height={196} width={313} 
                    />
                </DivFlex>
            </DivFlex>
        </Suspense>
    );
};

export default MiddleEbook;
