This script disables one of the most annoying features of the new YouTube UI: Split-Scroll, where the sidebar and the video player scroll independently.

Key Features:

Split-Scroll Killer: The sidebar is no longer "locked." It returns to the general page flow and scrolls together with the video and comments, just like in the classic interface.

Layout Stabilization: Removes YouTube's programmatic attributes that cause UI elements to behave erratically during scrolling.

Instant Execution: Uses a MutationObserver to intercept and block the split-scroll function before the page even finishes rendering.

Usage:
Just install the script, and the classic scrolling behavior will be restored automatically. No more "jumping" columns or sticky sidebars.
