Search hangs when searching a repeated substring with wildcard

See the jsFiddle here: https://jsfiddle.net/bwe0f44g/

var idx = lunr(function () {
  this.ref('name')
  this.field('text')
  this.add({
  "name": "long",
  "text": "Zlah_testZlah_Zlah_testZlah_testZlah_testZlah_testZlah_testZlah_testZlah_testZlah_testZlah"
});
})

window.search = function search(){
	var t0 = performance.now();
  var result = idx.search('*Zlah*');
  var t1 = performance.now();
  alert('Found '+result.length+' results in ' + (t1-t0) + 'ms');
}

Yes it seems that is quite a nasty bug that is preventing me from using wildcards. Thanks for your help!
