nextOnTargetClick doesn't work while animating in.

[ditproz]

I am using nextOnTargetClick on my tour, however I find that it fails to activate if the user clicks the button quickly.

In the case where the user starts the tour, the first step comes into focus (animating). If the user clicks (b) too quickly (while (a) is still animating), it doesn't force the tour onto the next step. However if they wait until the animation is finished, it works flawlessly.

Is there any way to remedy this issue?

NB: By animate, is simply mean fading into the UI.
