Clear started transitions overwritten by duration 0 transitions on the same property

Clear started transitions overwritten by duration 0 transitions on the same property

This patch ensures that transitions on properties don't start if they're
specified with 0s duration but have non-zero duration in prior transition
layers.

Example: "transition: all 1s, left 0s" should not start transitions on left.
