On kendo-react-layout: 7.3.0:
Drawer items are tab-navigable, but will not trigger the onSelect callback when the Enter button is pressed. I could not find any documentation in https://www.telerik.com/kendo-react-ui/components/layout/drawer/ or in https://www.telerik.com/kendo-react-ui/components/layout/drawer/accessibility/wai-aria-support/ denoting how to enable or implement this functionality, which would be required for Section 508 compliance.
Ideally, this would be functional out-of-the-box, and would not require a workaround such as implementing our own global event-handlers.
Please let me know how we should go about implementing this functionality, or when a fix has been released (or if a fix has already been released).
