Animator does not correctly parse transition durations with multiple values

[jonrimmer]

In order to determine the correct length of time to play a CSS-transition-based animation, animator.js attempts to parse the value of the transition-duration property of the element's computed style to a float value. However, it fails to account for cases where multiple transitions are specified. For example: transition-duration: 0.2s, 0.5s, 1s. Only the first value is parsed, which may be shorter than one or more than the others.

The result will be that the animation finishes before the transition is completed. If some action, such a DOM removal, is scheduled to take place after, it will result in the animation being cut off before it is completed.
