Describe the bug
When selecting or uploading an icon or picture for background use the dropdown never shows a preview. Therefore it's very difficult to design to my needs.

2. Select a "view" e.g. "home"
3. Scroll down to one of the devices of the selected view
4. Click dropdown menu for e.g. "Background image"
5. Dropdown and selection works but no preview is displayed

Expected behavior
Dropdowns should display previewa of icons and images
