MultiSelect (and the rest of the dropdown components) aria-controls attribute value does not match any existing DOM element id

Bug report

Reproduction of the problem

(bug report only)
1. Run this example: https://blazorrepl.telerik.com/cUaBGOOZ34pkp6wB57
2. Inspect the MultiSelect’s input.
3. Click within the component’s input area, to open its popup.

The issue is also reproducible in the other dropdown components: https://blazorrepl.telerik.com/GUurGmvw32oPqGYu03

Current behavior

(optional)
When the dropdown opens, an aria-controls attribute is applied to the MultiSelect’s input. Its value does not match any existing DOM element.

Expected/desired behavior

The value of the aria-controls attribute should point at an existing element (e.g., the popup’s list element: https://www.telerik.com/blazor-ui/documentation/components/multiselect/accessibility/wai-aria-support#multiselect-wrapping-element ). But in this case the MultiSelect is not bound to data and a list element is not rendered in the popup.

Environment

  • Kendo/Telerik version: 14.1.0
  • jQuery version:
  • Browser: [all ]

Just noticed that at least with the 15.1.0 release, the whole aria-controls attribute is totally gone?

An 'aria-activedescendant' does appear when opening the dropdown, but it also doesn't point to anything. This is marked as Completed, so will the 'aria-activedescendant' in the future point to an actual DOM element?
