This bugged me so much and yet I ended up noticing a simple workaround: keep the mouse in the top bar where the search box is.

By all UI logic this should not scroll as this element is not scrollable (it's the top bar above the scrollable content), but YouTube and Google in their infinite UX wisdom kept the scroll mouse events go behind the hovered element. I won't complain about this one too.
