Actual Results

The disabled state is not programmatically defined for “Previous” and "Next" button.
As a result, screen reader users are not able to understand the button's disabled state.

Expected Results

The screen reader should announce the disabled state for the button.

Add 'disabled' attribute when the button is in the disabled state. Ensure that 'disabled' attribute is removed when the button is in the enabled state via scripting.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available.
