I was using version 0.1.8 and I was using this test withFixHtmlEntitiesInExpressionSubscriber:

<!-- input--><div><imgsrc="{{ true ?"/b/x.jpg"}}"></div><!-- expected--><div><imgsrc="/b/x.jpg"></div>

It work fine with 0.1.8 but after upgrading to 0.1.9 or 1.0.0. this code stucks Twital in infinite loop (probably).
