<http://trac.webkit.org/projects/webkit/changeset/53420> introduced a repaint regression. On this page, if you slowly scroll the bottom of the comments field into view, the bottom does not paint. This is probably because the repaint logic considers the first and last line boxes, and the next-to-last line box has visible overflow that is greater than the last’s, which is just a TrailingFloatsRootInlineBox.
