The issue here seems to be that m_frameRect of the table cell is not relative to its container for some reason, but to the table.
The issue here is that RenderTableCells have frame rects that are relative to the RenderTableSection, but their container is the RenderTableRow. I have a fix for this and hope to post it tomorrow.
