Next.js Image Component Not Maintaining Quality When Using Progressive JPEGs

I can't seem to get I'm experiencing an issue with the Next.js Image component (version 12.0.7) where images encoded as progressive JPEGs are not rendering with the expected quality. Instead, they appear to be significantly blurred or pixelated compared to when I serve them directly using a standard `img` tag. I've attempted to set the `quality` prop to various levels, from 75 to 100, but the rendered output doesn’t seem to change. Here’s a simplified example of how I’m using the Image component: ```javascript import Image from 'next/image'; const MyComponent = () => { return ( <div> <Image src="/path/to/progressive-image.jpg" alt="A sample progressive JPEG" width={800} height={600} quality={100} // I've tried various quality settings layout="responsive" /> </div> ); }; export default MyComponent; ``` The progressive JPEGs are being generated using a tool like ImageMagick, and I’ve confirmed that the images look great when viewed outside of the Next.js environment. To troubleshoot, I also tried setting up a direct `img` tag: ```html <img src="/path/to/progressive-image.jpg" alt="A sample progressive JPEG" width="800" height="600" /> ``` The quality is significantly better in this case, which leads me to believe that the issue lies within the configuration of the Next.js Image component itself. I've checked the Next.js documentation, and there doesn’t seem to be any mention of limitations regarding progressive JPEGs. Is there a known issue or a workaround for ensuring that progressive JPEGs maintain their quality in the Next.js Image component? Any insights would be greatly appreciated! This is my first time working with Javascript 3.9. Thanks for any help you can provide!
