Currently Kendo UI for Vue Native AutoComplete does not support virtualization yet there are lots of scenarios where it is needed as well.  

Describe the bug
autocomplete triggers change event again on blur

To Reproduce
Steps to reproduce the behavior: https://stackblitz.com/edit/pallqy?file=src%2Fmain.vue

type a in the input
select 'Austria' for example - change event is triggered
click outside of the autocomplete - change event is triggered again

Expected behavior
the second change event is not triggered if the value is not changed

Currently, in the Native AutoComplete, we don't have some functionalities that are available in the Wrapper component. 

It will be really useful if we can:

• Select multiple items in the AutoComplete
• In addition to the above, to have the separator property that is available in the AutoComplete Wrapper
