I have problem with the listview.
And i see same problem on the example in Sencha page.
You can take a look at the second sample in this site, when the list is long you can not swipe it down.

I'm using Chrome lastest version 60.0.3112.101 on my laptop (not mobile device).
If i use Safari or Microsoft Edge, there's no problem.

It's weird to ask Sencha Touch work on PC or Laptop, but i really need this.
Please help me !
