* rendering/RenderBlock.cpp:
(WebCore::RenderBlock::positionForPointWithInlineChildren): To prevent hits after the last
line on a given column from returning the next line in the next column, added a check if
the hit occurred within the pagination strut of a line. Covered by the first test.
(WebCore::RenderBlock::adjustPointToColumnContents): Added clamp-to-column logic for the
block-axis case. This prevents hits near the bottom of the top half of the gap from bleeding
into the top of the next column. Covered by the second test.
