4. Open the Rules panel and add 'animation-iteration-count: 5;' in the #box1 rule.
5. Switch back to animation panel and click on the Rewind button.
6. Click on the play button and wait until the animation is played the second time.

From bug 1120899 comment 14:

At first sight, it looks like changing the duration, delay or iteration-count only works some of the times, and sort of randomly. Testing this a little more showed that:
- if the animation is paused (either because you pressed the rewind button, or pause button while it was playing): then changing any of these things in the rule-view does refresh the animation-panel correctly
- if the animation has ended (you just let it play until the end): then changing these things does *not* refresh the animation-panel.
Pressing play/pause/rewind does force a refresh so you see the changes then.
The fact that the scrubber is not displayed is related and should be fixed in the same bug.
