Picture orientation metadata not honored

[ook]

When I upload a picture with an a specific orientation metadata, File doesn't honor it and display it the wrong way (in preview AND thumbnails).

If I download from cozy and open from a orientation friendly software, it's opened the correct way. (and if I reupload, Cozy will have it the wrong way again).

Picture, thousand words:

Just seen that only FF can endorse it at this time easily. The other solution would be to search and read the EXIF for each IMG in view and manually do the rotation if CSS directive is unavailable.
