Preferred subtitle language being ignored
Describe the bug When I was looking into issue #10829, I noticed that the subtitle selection behavior between the web client within a browser, and Jellyfin Media Player (JMP) was different. For my testing I used a Matroska (mkv) media file, containing many different subtitle tracks in many different languages. In the browsers that I used (Edge & Firefox) it selected the Dutch subtitle track. In Jellyfin Media Player it selected "Off". My preferred subtitle language option is set to "Dutch; Flemish", as such the expectation is that a Dutch subtitle track will be selected by default.
To Reproduce Steps to reproduce the behavior:
- Have a file that has no default and no forced subtitle tracks and contains different languages
- Set the "Preferred subtitle language" option to one of the languages you want to test
- Make sure "Subtitle mode" is set to default
- Save
- Navigate to the episode file and validate what language is selected
Expected behavior The language that is configured as "Preferred subtitle language" should be selected.
Actual behavior The language track "Off" is selected.

is it possible this is an off-by-one index problem or is it like, more complicated than that?
I wouldn't expect it to be an off by one index issue as the Dutch subtitle is not the first one in the list, nor the last.
I have a similar problem. If I watch a series episode that has no subtitle but the next one has a forced subtitle, the selected subtitle remains OFF when the next episode starts and you have to manually change the subtitle to forced for each episode EVEN THOUGH the subtitle options are set to default and you normally takes the option from the MKV container if the forced flag is set. This is super annoying. Is this related to this bug?
I tested the behavior on the PC with the current desktop, on my LG Oled and in Chrome, Edge and Firefox + on a Samsung Galaxy S23 and a 4k FireTV Max...
It's really stupid if you have to reactivate the subtitles against the settings every time for every episode...
