Combobox options remain filtered after selecting an option and leaving control

[ksCookj]

Describe the bug
When you select a value of the combobox via filtering. Once you tab off the control or leave focus, coming back and clicking the expand arrow still shows all options as filtered.

To Reproduce
Use first example here: https://www.telerik.com/kendo-angular-ui/components/dropdowns/combobox/filtering/

1. filter for "small" and tab off, selecting a value in the process
2. go back and expand combobox by clicking the expand arrow
3. All options are still filtered

Expected behavior
After filtering and leaving control (selecting a value in the process), going back and clicking the arrow to expand combo box should display all options.
