Dolphin JPEG image preview

Preview images in KImageFilePreview for JPEG files are always scaled to the widget size - no matter how how small the jpeg is. PNGs are not scaled. Dolphin and Krusader are affected. See screenshot.

I tracked it down to thumbnail/jpegcreator and its maybe caused by https://git.reviewboard.kde.org/r/129851/

Version:
KDE Frameworks 5.33.0
kio-extras 17.04.0

Alexander, could you please upload the patch using https://phabricator.kde.org/differential/diff/create/

It is missing from the link in comment #1, and it looks like reviewboard does not work; the review is not even listed at https://git.reviewboard.kde.org/users/volkov/
