lost taps on triggers when playing on iPad

iSpring Pro 7, published to HTML5 and playing on iPad: I've got a trigger for a slide animation. The first time you visit the slide it works perfectly, however if you return to the slide during the same session, the first tap seems to be ignored, and you need to tap the object a second time in order to activate the trigger.

As far as I can tell this is repeatable, and doesn't reflect the behavior in PowerPoint. I've tried changing the trigger to 'start on click', 'start after previous' and 'start with previous' but this doesn't seem to make any difference.

Anyone else noticed this? Any workarounds?
