Subitltle issue in 16.6.7

-A clear description of your problem:
I noticed with this release that once I toggled on subtitles in an mkv (happens for videos that have built-in subtitles and those where it's a discrete file) and then toggled it off, that when toggled on again the subtitles don't actually display. It's as if they're still off, which they may well be despite being on. Restarting the player fixes it, but it will happen again as of the second toggle.

Win11

-Mention which version of the codec pack you are using.
16.6.7 only. This is definitely new behavior that I've never seen over years until now. Reverted to 16.6.5 and then upgraded to 16.6.6. All is well again.

Will be fixed in next version.

Looks good in 16.6.8, thanks.
