You can't hold and drag the picture in Chrome. However, you need to click on the handle (#icon-sort) for sort.
But you can drag and drop the picture on the Edge and when you drop it, it loads a file in the .url extension.
To Reproduce
- Download starterkit
- Login panel with Edge Browser
- Enter an album
/panel/pages/photography+sky
- Drag (over the image, not from handle) any image and drop same field area
