:)

Can say lastRect.right() instead of x() + width().

> Source/WebCore/rendering/RenderBlock.cpp:1331

You’ve already defined and initialized this outside.

> +                int overflowBottom = style()->isLeftToRightDirection() ? max(height(), lastRect.y() + lastRect.height()) : 0;

Can say lastRect.bottom() instead of y() + height().

> +    IntRect firstColRect = columnRectAt(colInfo, 0);

I don’t think this is used.

ZOMG whitespace

failing tests on Qt

Two tests seem very strange on Qt. Could you check it, please?

[Jessie Berlin]

At least two of the new tests have different actual results on the Windows 7 Release Test bots:
