Before 3b22ffc, when with-animation's componentDidMount was called, the child ref was already set, but the change in the timing of setIsLive caused it to now be null at that point, so it's not possible to register an event listener for child events.

To avoid the issue, I've moved with-animation's event handling into animate, where the child ref is already set.
