Code review comment for lp:~ubuntu-sdk-team/ubuntu-ui-toolkit/no-dFdy-trunk

I discovered a problem with this MR, see this screenshot: https://www.dropbox.com/s/uy6sro2spmyiq53/Screenshot%202015-08-19%2000.32.46.png?dl=0

On the left you see the rendering without the extension (you would see that in the emulator), and on the right, the rendering with extension. The fix that we have for rendering without the extension has a shadow at the bottom of the shape that the correct one only has at the top.
