Wiki preview + markdown compiler issue

Preview through preview button on right top of a editor shows correct preview.
But once saved it shows different markdown output.
Maybe wiki not using same markdown compiler for preview and actual output.

####Try this markdown code

#Titile 1
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris quis arcu sed sem consectetur faucibus vel a nisi.
###Title 2

####Title 3 `code`

some awesome random code
