Menu colours are confusing

The colours used by VLCPlaybackInfoTVCollectionViewCell are a bit off when Dark appearance is active. Sadly I could not get a screenshot directly from the device, but one can easily reproduce the issue on 6ad83679 by following the next steps:

1. Make sure tvOS is using the Dark appearance.
2. Open any video file, and pause it.
3. Open the playback info panel by swiping down the remote.[1]
4. Change between options available in the Track Selection tab.

The unfocused colour will then change after items are focused at least once.

[1] One may also notice the Track Selection tab does not automatically appear before you switch to another tab and then go back to Track Selection. I intend to send another patch for this issue ASAP.
