Vertical Scrollbar disappears after dynamically adding Window (dialog)

[Ruairi]

I'm using latest build of Kendo UI MVC (2017.3.913) and I have a complex form which contains TabStrip.
Each Tab within the TabStrip contains PanelBar with multiple expandable\collapsible panels that allow me to view and edit data. When I expand a Panel the vertical scroll-barallows me to scroll down to view details etc.. Everything works fine so far.

On the form I also dynamically add a Kendo Window (dialog) and do various things like - Select Address,Select Person etc.. Dynamically creating it is a must - I destroy it after every time i use it. For demonstration the javascript function below creates the Window what I require to show the problem:

 

//This dynamically creates a Window (but donst show it yet)
function testCreateWindowDynamically()
{
  $(document.body).append("<div id='myContainerDiv' class='dlgContainer'></div>");
  $("#myContainerDiv").append("<div id='myDialogWindow' class='dlgDialog'></div>");
  var dialog =
    $("#myDialogWindow").kendoWindow({
      title: "",
      modal: true,
      actions: ["Close", "Minimize", "Maximize"],
      visible: false
    });

  $("#myDialogWindow").data("kendoWindow").maximize();
}

 

When I run this the vertical scroll bar on the tab strip disappears and I cant scroll down to view content not displayed on screen. Why is the vertical scroll bar disappearing?

After some testing on our previous release which used the previous version of kendo UI (v2017.2.504) this worked correctly. So basically the new version of Keno UI must have added this bug.
