Scrollview and navigation problem

Hello dear Webix team, I am using Jet-0, I have

{ view: "scrollview", 
body: {
      rows: [
            {$subview: true}
]
}} 

in my views/top.js view, same like in your repo in views/app.js

when app is first loaded everything is fine, but after I navigate to any other subview it is compressed to left upper corner and became normal again after page resizing, but after deleting view: "scrollview" everything is working fine again"

Please try to use the solution from here -

Also, be sure to set size on scrollview or on its content, as if both sizes are not defined scrollview will not work correctly.
