1786893 - about:processes table headers are not accessible and cannot be sorted with keyboard

Status: NEW

(Toolkit :: Performance Monitoring, defect, P3)

Description

[Anna Yeddi [:ayeddi]]

Steps To Reproduce:

• open about:processes
• navigate to the first table row on any column using keyboard alone (by pressing Tab or Shift+Tab), focus it
• activate this control by pressing Enter or Space
• activate a screen reader
• navigate to the first table row on any column, focus it
• activate this control by pressing Enter or Space

Expected:

• Table header cell receives keyboard focus, the sorting button itself and its focus outline are visible
• Screen reader describes the button, its role and state (sortable)
• User can activate this control by pressing Enter or Space
• Table rows are sorted by the column that was activated
• Screen reader announces change of state and order of sorting (ascending/descending)

Actual:

• Table header controls are skipped by a keyboard (they cannot be focused)
• Screen reader treats the sortable header controls as inactive table headers that cannot be sorted
• Sorting can only be performed with a mouse click, nothing happens when Enter or Space are pressed
• Screen reader does not communicate which column is used for sorting and what the sorting order is

The same would apply for these controls on the about:performance screen.
