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
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
