3D CSS transform, jagged edges in Firefox

Question

Similary to "css transform, jagged edges in chrome", same occurs with Firefox on 3D transforms, eg: http://jsfiddle.net/78d8K/5/ (<- remember: Firefox)

"Workaround", add a transparent outline attribute:

outline: 1px solid transparent;

border: 1px solid white;
