This reminds me that MS used to have an export to HTML feature in PowerPoint, but it was very IE specific and they removed it in PowerPoint 2010 I think instead of fixing it. This is also true for Word/Excel, to the point that even in the 2013 release you can set it so that it generates HTML that even MS's own IE10 won't render properly.
