    Description

      Issue
      Context change - Hiding/showing a column in the assignment grading screen does not announce the change to the user. It would be useful to rely on aria-live="polite" to tell screen readers if the zones are "live" (opened or closed) or provide another similar mechanism.

      Standard Level
      WCAG 2 3.3.2 (A) http://www.w3.org/TR/UNDERSTANDING-WCAG20/minimize-error-identified.html

      Impact
      Serious

      Example Link
      http://demo.moodle.net/mod/assign/view.php?action=grading&id=41&thide=userid

      Test Steps

      1. Login as teacher
      2. Access CF101
      3. Click on assignment
      4. Click on grade attempts
      5. Close a column in the report and notice nothing is announced.
