Description
Adds guidance to the ARIA
tabpanelrole page on handling panels that have no content to show. It advises against leaving a focusable emptytabpanel(a focus dead-end for keyboard and assistive-technology users), and suggests removing the tab/tabpanel when there is genuinely no content, or giving the panel a placeholder message such as "No data".Motivation
Provides the practical guidance requested in the linked issue so implementers handle empty tabpanels accessibly.
