"Search in Software" dialog in Nautilus does not find any applications on Fedora Silverblue
When opening an unknown file type in Nautilus and clicking the "Search in Software" button, GNOME Software is opened, but no actual application for the given file type is found. Everything works fine when right clicking the file, selecting "Open With Other Application" and clicking "Find New Applications".
Reproducible in:
Fedora Silverblue Rawhide (It seems to work fine on regular Fedora Rawhide.)
