Here’s how I would write this:

    return {
        verticalScrollbar() ? verticalScrollbar()->occupiedWidth() : 0,
        horizontalScrollbar() ? horizontalScrollbar()->occupiedHeight() : 0
    };

I like reducing the number of times we have to utter the type name IntSize, and I also like the formatting better with the braces.
