screen reader not announcing richselect options

Webix JS
#1

Hi,

Please see following snippet sample. https://snippet.webix.com/h0l9h1fm

there’s a basic richselect and a datatable with button column using a richselect editor.

keyboard navigation works fine. I can

  1. tab to the action button,
  2. press enter,
  3. use up/down arrow keys,
  4. press enter to select an option.

however, if i turn on voice over (VoiceOver Keyboard Shortcuts on a Mac | Screen Reader Keyboard Shortcuts and Gestures), screen reader does not announce options as I use up/down arrows in step 3.

options are announced as expected in the basic rich editor but not in the action button popup.

how can I get the screenreader to announce options in action button popup?

Thanks
