DropDownList (Select) doesn't calculate cascade change properly when focus is controlled

The "change" event on DropDownList is being triggered when the value change of the widget is via API and not triggered by user interaction.

Steps to reproduce:

https://dojo.telerik.com/oKeBEZUN

  1. Manually select a value for category (like Category 4); a console item should be written for user change
  2. Click the "change doc to empty" button which clears the category
  3. Click the "change doc to values" button which programmatically sets the category

Expected: a log item is NOT added because the change was programmatic and the log item is triggered on "change"
Actual: a log item is added even though the value change was programmatic

The change detection inside the select widget is faulty in that it seems to be effected by focus/blur state.

This issue was found after upgrading kendo UI.  I believe the issue was introduced in 2018.1.117
