DropDownTree TagHelper renders input instead of select element when checkboxes are enabled

[kendo-bot]

Bug report

The DropDownTree TagHelper with enabled checkboxes does not submit the selected options when it is bound to a Model property.

Reproduction of the problem

1. Define a DropDownTree TagHelper as a form editor and and enable its checkboxes.

2. Bind the editor to a Model property (an array of integers).

3. Submit the form and examine the submit request payload. The values of the selected items are missing.

//Model
public class TestFormModelClass
{
  public int[] MonthsSelectedIds { get; set; }
}

//View
@model TestFormModelClass

<form method="post">
  <kendo-dropdowntree for="MonthsSelectedIds" 
      check-all="true"
      datatextfield="Month"
      datavaluefield="Id">
      <hierarchical-datasource type="DataSourceTagHelperType.Custom">
                <schema>
                    <hierarchical-model id="id"></hierarchical-model>
                </schema>
                <transport>
                    <read url="/api/items" />
                </transport>
      </hierarchical-datasource>
      <checkboxes check-children="false" name="CheckedMonths" enabled="true" />
  </kendo-dropdowntree>

  <button type="submit">Save</button>
</form>

Expected/desired behavior

When the DropDownTree TagHelper with checkboxes is used as a form editor, the values of the selected items must be submitted as expected to the server.

Workaround

Use the HtmlHelper version of the DropDownTree
