For rightward and downward overflow the spec says: Let x be max(0, min(x, viewport scrolling area width - viewport width)). Let y be max(0, min(y, viewport scrolling area height - viewport height)). Previously, those operations were reversed, which created negative overflow even when the overflow direction was downward. This change ensures that Servo matches spec behavior.

The latest branch includes the new hash from update-manifest. |
