When viewing Galleria with the default theme in fullscreen mode,
some vertical images wrongfully display horizontally. This does not
affect all vertical images, but quite a few.

When not in fullscreen, all images display as intended.

Is there a reason why this happens? A fix?

Current JS:

var flickr = new Galleria.Flickr();
  flickr.setOptions({
    max: 40,
    description: false
});

flickr.user('80936234@N05', function(data) {
  data.sort(function() {
    return (Math.round(Math.random())-0.5);
});


Galleria.run('#galleria', { 
  dataSource: data, 
  autoplay: 7000, 
  transition: 'slide',
  extend: function() {
    $('#fullscreen').click(this.proxy(function(e) {
      e.preventDefault();
        this.enterFullscreen(); 
      })
    );
   }
  });
});

Galleria.ready(function() {
  var gallery = this;
  this.addElement('exit').appendChild('container','exit');
  var btn = this.$('exit').hide().text('Close').click(function(e) {
        gallery.exitFullscreen();
  });
  this.bind('fullscreen_enter', function() {
    btn.show();
  });
  this.bind('fullscreen_exit', function() {
    btn.hide();
  });
});
