Image with different rotation when proxy is activated or not

When I import a particular picture taken with an iphone ( IMG_6296.JPG in attachment), the image appears vertical in the project bin and in the project monitor. If I activate the proxy for this image, the image is still vertical in the project bin but now horizontal in the project monitor. Which means if I use proxies to edit my video, the image looks fine because I see it horizontal like I want it to be, but when I calculate the final video the proxies are not used and the image appears vertical in the final output. So the final renders is different than what I see on my timeline.

My guess is that kdenlive and the proxy calculator use the EXIF data differently to rotate the image.

STEPS TO REPRODUCE
1. start a new project
2. add IMG_6296.JPG to the project bin
3. add IMG_6296.JPG to the timeline
4. Click on the timeline to preview the timeline in the monitor
    Note that the image (IMG_6296.JPG) appears to be vertical.
5. Click the image in the project bin and activate proxy for this image
    Note that the image is now vertical in the project bin, but horizontal in the monitor.

OBSERVED RESULT
The image changes its orientation when proxy is activated or not

EXPECTED RESULT
The image should not change orientation because I activate proxy on it.

SOFTWARE/OS VERSIONS
