Reviewed by Antonio Gomes.

Source/WebCore: 

When 2 anchor elements span more than one line each, and one ends on the same line that the
second starts on, the rects reported by their renderers are overlapping. When handling
2 overlapping nodes, check for this case, and don't assume that one of the nodes is on a higher layer.
