STEPS TO REPRODUCE
1. Install an icon theme where the 16x16 and 22x22 icon sizes can easily be distinguished from sizes 32x32 and over.
2. Open dolphin and zoom out to size 16x16 or 22x22. The view mode does not matter. It also does not matter whether or not scaling has been enabled in 'Display configuration' (tried using both Wayland and X11).
3. Enable 'show previews'.


OBSERVED RESULT

With show previews enabled, Dolphin will scale down a larger folder icon for folders containing files. The application will use the correct icons for folders that do not contain files. This behaviour is not exclusive to a single folder type: it happens to 'general' folders as well as the documents, downloads and pictures folders in the user's home folder - and assumedly other folder types, if present, as well. If show previews is not enabled, Dolphin uses the correct icons.

EXPECTED RESULT

Dolphin uses the correct icon irrespective of whether show previews is enabled or not.
