When I run a transition using $animateCss with a delay set in the params, the transition will jump suddenly sometimes, especially when delay = duration.

I don't think this is supposed to be happening.

This issue is easily fixed by setting transition-delay in the object's CSS to any value at all (which gets ignored). I am not sure why no-value behaves differently from transition-delay: [any value].

A general workaround for anyone having trouble is to put the following at the top of your CSS:

* {
  transition-delay: 0s;
}

since this is the default value for transition-delay anyway.
