Reproducible in the demos: https://demos.telerik.com/blazor-ui/dropdowntree/overview
(optional)
For a brief moment the filter input in the dropdown appears focused, but then the focus moves to the first item in the list. If the user clicks the “down arrow” icon to open the dropdown, the filter input is focused as expected.
The filter input is focused regardless where in the component the user clicks.
