I believe there is a bug. I can't get naturalWidth / naturalHeight in Firefox. Neither Safari nor Chrome has this problem.

JavaScript code:

let image = document.querySelector("img"); console.log("natural width=" + image.naturalWidth + ", " + "natural height=" + image.height);

The code printed a value of 0 in Firefox whereas browsers printed the respective width and height of the image.
