That allow EventHandler process wheel event on corresponding navigable. For top-level navigable that means IPC call to let chrome know about scrollbar position update. Fixes https://github.com/SerenityOS/serenity/issues/23599 Fixes https://github.com/SerenityOS/serenity/issues/23493 Fixes https://github.com/SerenityOS/serenity/issues/23966
