Steps to reproduce:

in a HTML document, an element with background-image set to a JPEG with EXIF metadata rotation, as in https://jsfiddle.net/5mnfsaud/ . More examples can be found in https://github.com/recurser/exif-orientation-examples
Adding CSS attribute image-orientation: from-image; makes no difference.

Actual results:

As seen in https://jsfiddle.net/5mnfsaud/ - the EXIF rotation information is ignored in Firefox (in Chrome it automatically is rotated to match the metadata).
Setting image-orientation: from-image in the img element CSS does result in them being displayed correctly - but for the div it does not.

Expected results:

I think background-images should respect EXIF metadata. Especially if you specify to use image-orientation: from-image.
