Title basically says it all. Issue can be easily observed in the basic Multiselect with virtualization example:

1. Open the dropdown
2. Scroll to the bottom end
3. Close the dropdown
4. Open it again - popup's scroll position is incorrect and therefore shows blank.

What seems strange is that I cannot reproduce this issue with the combobox virtualization, although I found a somewhat similar bug submitted for the combobox - https://github.com/telerik/kendo-react/issues/1450 

We have received feedback from our user group indicating a need for keyboard-based selection for items that are not in sequential order. Currently, keyboard selection functionality only allows users to select items in a continuous sequence. For example, when using Ctrl+Click, all items in between are automatically selected.

Is supporting non-sequential item selection via keyboard something you plan to implement? If not, could you suggest the best approach or alternative solutions to address this requirement?

Current behavior

After the latest accessibility improvements available with R1 2023 of the KendoReact library, the aria-required attribute is missing in most of the DropDowns.

Expected behavior

The aria-required attribute should be rendered in the DOM once the MultiSelect definition contains a required attribute like this:

  <MultiSelect required data={sports} onChange={onChange} value={value} />

Minimal reproduction of the problem with instructions

1. Open this StackBlitz example
2. Inspect the MultiSelect component to see that the aria-required in not rendered
