use timeout props without exit time

[LiuuY]

Do you want to request a feature or report a bug?

bug, maybe?

What is the current behavior?

if I use timeout props without exit time, eg,

<CSSTransition
  key={id}
  timeout={{
    enter: 300,
    // no exit time
  }}
  classNames="fade"
>

Click the red X button, after the animation, the element that should (?) be removed from DOM tree is still there.

Is this a feature or a bug?

version: 2.2.1

I think this is unexpected behavior. I think the expected behavior should be to raise an error or warning, because I don't know if there is a sensible default value we could add for exit. (Maybe 0?)

Solved with #464. exit timeout now defaults to 0, which I consider intuitive behavior.
