Description

Relates to elastic/kibana#214104

When navigating EuiDataGrid header cells with screen readers (e.g. NVDA on Windows) it will output a duplicated text for a sorted cell.

This is due to the cell having both an aria-sorted attribute and an additional screenreader-only hint text linked via aria-describedby.

We should check if we can remove the additional hint text. There might be reason for having it in case aria-sort might not be supported consistently across assistive technologies. This requires testing if aria-sort is output as expected by at least the main screen readers (JAWS, NVDA, VO).

Steps

• test the sorted cell in the EuiDataGrid header in the most common SR combinations:
  • Chrome + NVDA
  • Chrome + JAWS
  • Firefox + NVDA
  • Firefox + JAWS
  • Safari + VoiceOver
• update the conditions in packages/eui/src/components/datagrid/body/header/column_sorting.tsx
• test the new conditions with screen readers
• verify the SR output in Kibana > Discover
