When user inputs text that does not match any of the items in the data source and presses the down arrow key, the "suggestions" drop down list opens up with an empty list when the configuration option is: 'noDataTemplate: false'.
This seems to be a regression since it appears to be working in an older version:

Note the kendo version (2016.3.914).
Same demo with newer version of kendo (2018.2.620): http://dojo.telerik.com/ehaDEsIq
1. Type a string in the AutoComplete that does not match any values in the data source, e.g. ("123")
2. Press the "down" arrow key to open up the suggestions dropdown.
The suggestions dropdown opens up with no items -- it should not be opening up at all.
Behavior in (2016.3.914) is that the dropdown does not open when using the arrow keys if the typed in text does not match any of the items in the suggestions list. [Correct]
Behavior in (2018.2.620) is that the dropdown does open with an empty list when using the arrow keys if the typed-in text does not match any of the items in the suggestions list. [Incorrect]
