iframe class ignoring height/width params since upgrade

We use Easy Fancybox for a couple of iframe popups as well as the usual images and whatnot.

On this page: http://baynature.org/trail/briones-to-acalanes-ridge-top-hike/

The “Get Directions” button below the map has been working great for a while, but since the upgrade a week ago, it’s ignoring the size params we have in our code.

That popup is created with this code:

var a = jQuery("<a></a>").
      attr("href", "http://embed.transitandtrails.org/embed/plan/location?arrive=true&lat=" + coordinates.latitude + "&lng=" + coordinates.longitude).
      attr("class", "fancybox iframe {width:380,height:540}");

    a.fancybox({
      hideOnContentClick:false,
      hideOnOverlayClick:false,
      autoScale:false
    }).trigger("click");

I tried changing the class to “fancybox-iframe” but that didn’t help. Did the implementation of size parameters change? I can’t seem to find any documentation to that effect.

Thanks for any advice!
