bug for image 2/3 ratio size when max height is 480px

[tshak93]

When I upload a 2/3 size image (example: 700/1050px, 1000/1500px, etc.) and in the media settings (/options-media.php) I set the maximum height and maximum width to 480px, the medium size image (which measures 320px x 480px) is never displayed on wordpress.

this problem exists only for images resized in medium size. everything seems OK for small and large size.

I think this bug exists since several versions.
