Bug Report: Variants' audios aren't loading from cli-opened-.fnfc

[tposejank]

There is a command to open the chart editor and a specific chart just with the CMD:
./Funkin.exe --chart backups/some_chart.fnfc

However this command has a few downsides, as when using the difficulty menu to change to a different variant/difficulty in another variant, the audio of the variant will not load, and in consequence, may cause issues while charting.

In the following video, each variant has different audios. However, when changing the chart/variant, the only time audios will load again is when switching to another variant, then back to the default one. The chart editor will freeze like usual, and attempt to load the default variant's audio files.

I may ask you to check out this bug, I dont know if its because of the skipping straight to the editor, but please find out what causes this pwetty small issue 🙏 (it is useful for me)
(I probably would say, its because of loading straight from an .fnfc. If that would be the case, then opening an .fnfc with the File tab may cause this same issue. Ill investigate that)

Update: maybe this is caused because the variant audios arent included in the fnfc?

I loaded an fnfc with variant's audios present, but it will still refuse to switch instrumentals.
