STEPS TO REPRODUCE 1. Use SaveFile with "current_folder" and "current_name" to save a file with an extension. 2. Use SaveFile with "current_file" to save over the previous file. 3. Notice that it is offering to save without the extension. OBSERVED RESULT The dialog resulting from SaveFile with "current_file" set fills the filename field without an extension. EXPECTED RESULT Either the filename field should have the extension of the value provided by "current_file" or the filter should automatically select the filter that matches the given extension. SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: Fedora 42 using GNOME desktop with KDE portals. KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.6.0 Qt Version: 6.9.0 ADDITIONAL INFORMATION I found this while working on SDL: https://github.com/libsdl-org/SDL/pull/13007 I worked around it by setting the "current_filter" field.
