test case

See the test case.

[Ryosuke Niwa]

The problem is that RenderBlock::positionForPoint assumes that the lastChildBox is not positioned.

if (lastChildBox() && contentsY > lastChildBox()->y()) { 
    for (RenderBox* childBox = lastChildBox(); childBox; childBox = childBox->previousSiblingBox()) { 
        if (isChildHitTestCandidate(childBox)) 
            return positionForPointRespectingEditingBoundaries(this, childBox, pointInContents); 
    } 
} else { 

+mitz since this code was added in http://trac.webkit.org/changeset/42467.

Nope. My patch is fine. I was commenting out some code to verify my test and had forgotten to rebuild before running the test.
