Bit fiddly, but this matches BasicLayers fairly closely.

QA Whiteboard: [good first verify]
I was able to reproduce this bug on Nightly 33.0a1 (2014-06-30), using Windows 7 x64.

Verified fixed on Windows 7 x64 using Nightly 35.0a1 (2014-10-09).

This fix can be marked as verified.

I also noticed a strange behavior: the card shakes when is turned on the opposite side. Is this effect expected?
