22680	Check data.height and data.width before displaying dimensions	nacin	nacin	"A .ico file has either `image/vnd.microsoft.icon` or `image/x-icon` as its mime type. (Likely the latter due to wp_get_mime_types(), even though the former is canonical.)

This means it thinks it is an image. But, it doesn't have stored dimensions because in PHP we don't process icon files. That ends up with an awkward, lonely '×' where the dimensions sit, and it looks like a removal button if anything.

There might need to be other checks for icons, but I'm not really concerned about those edge cases. Even wp_attachment_is_image() simply let's `^/image/` pass, despite also checking the extension."	defect (bug)	closed	normal	3.5	Media	3.5	normal	fixed	has-patch commit
