Image files that have a different file extension than mime Type f.e. exempleimage.jpg with a content mime type image/webp . will not not show a thumbnail or a preview in the info panel. In the file property the content type is correctly stated but not used to handle the file. STEPS TO REPRODUCE 1. take a .webp and rename it with a .jpg extension. 2. the correct behavior happens when you delete the extension or the file name before the extension. 3. OBSERVED RESULT the thumbnail vanish and if you have sorted by type it jumps to another position EXPECTED RESULT nothing should happen SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
