Actual Results

The "This comment will be viewable by all users" expandable link does not have a programmatically defined expandable state. This link does not use an aria-expanded attribute. As a result, users of assistive technologies found it challenging to understand the functionality associated with this element.

Expected Results

When elements expand or collapse a particular content, make sure that they have a programmatically defined expandable state. Use the “aria-expanded” attribute on the expandable elements and update the “true” and “false” values appropriately. Make sure that the value is set to “true” when the elements are expanded and “false” when they are collapsed.
