Keeps YouTube's video volume perfectly in sync with the volume slider, preventing YouTube from capping the volume below 100% even when the slider is maxed out.
Fixes YouTube’s volume slider so that the actual video volume always matches the visible slider position. Prevents YouTube from lowering the volume internally (e.g. limiting it to ~60%) even when the slider is at 100%. Ensures accurate, full-volume playback when the slider is maxed out, and smooth syncing across all values.
