Fullscreen Issue with YouTube Videos in FluentPlayer

I noticed that YouTube videos embedded via FluentPlayer were automatically opening in fullscreen mode on mobile & desktop devices.

After investigating, I found that the player was rendering YouTube embeds with:

playsinline=0

As a temporary fix, I edited player.php and forced the playsinline attribute to always be present:

echo 'playsinline';

After making this change, YouTube videos started playing inline correctly instead of opening in fullscreen.

Has anyone else experienced this issue? It might be worth checking whether playsInline is being passed correctly to the Vidstack/YouTube provider.
