Screenshot of extensionless mkv file opened in haruna

SUMMARY
When an mkv file does not have a file extension, it does not play when opened. mp4 does not have this issue. Adding (afaict) any file extension, even if it is wrong, works.

STEPS TO REPRODUCE
1. Download/find an mkv file
2. Remove the .mkv at the end
3. Open in Haruna

OBSERVED RESULT
See attachment. Haruna window opens, but no file is played. View is afaict the same as opening haruna without a file

EXPECTED RESULT
Filetype is detected automatically and file is played (like with mp4)

My bad Frameworks version is 6.19.0, and the nightly flatpak uses Qt 6.9.3.
System Qt version is 6.10.0 though.
