1.2.0-rc.3 ngAnimate is really buggy with ng-class

[nosideeffects]

If you use ng-class with ngAnimate, to say animate left or right conditionally, ngAnimate 1.2.0-rc.3 often skips the animation entirely, whereas it seemingly always executes properly in 1.2.0-rc.2.

Just revert back to 1.2.0-rc.2 in the above example and see the buggy behavior disappear.

So yes this is a bug. What's going on is ng-class is competing with ng-show and it only shows up when the direction is set or changes. This is why it shows up on the first value. There's another issue open right now that is present due to this bug and I'm working on a fix.
