DropDownTree TagHelper renders DropDownList

[aleksandarevangelatov]

Bug report

When using the DropDownTree TagHelper a DropDownList is rendered instead of a DropDownTree

This is a regression introduced with v 2021.3.914

Reproduction of the problem

The following code will render a DropDownList instead of a DropDownTree:

<kendo-dropdowntree name="dropdowntree" datatextfield="FullName">
        <hierarchical-datasource>
            <transport>
                <read url="https://demos.telerik.com/kendo-ui/service/Employees" datatype="jsonp" />
            </transport>
            <schema type="json">
                <hierarchical-model id="EmployeeId" has-children="HasEmployees">
                </hierarchical-model>
            </schema>
        </hierarchical-datasource>
    </kendo-dropdowntree>

Expected/desired behavior

DropDownTree TagHelper should render DropDownTree.
