Describe the Bug

If original image is 800px width, I have to set 800-1px?
/_image?href=...origWidth%3D800%26origHeight%3D535%26origFormat%3Dwebp&w=799&f=webp 799w

If I set exactly 800, same as the original image width, it will choose the previous width which is 512.
/_image?href=...origWidth%3D800%26origHeight%3D535%26origFormat%3Dwebp&w=512&h=342&f=webp 800w

The same when I wanted to set 1024w to upsized the original image from 800px -> 1024px, it will remain at 512.

What's the expected result?

I think the width should be exactly as what it should be. 800 mean 800 and not less.

<Image 
	widths={[382, 512, 764, 1024]} 
	width={512}
	height={342} 
	src={whattoexpect} 
	sizes={`
		(min-width: 1024px) 1024px,
		(min-width: 764px) 764px,
		(min-width: 512px) 512px,
		100vw
	`}
	alt="What to expect" />
