Actual Result

When the user submits the form successfully the success message such as “Thank you for your feedback!)” gets displayed on a page which is not conveyed to the screen reader user. As a result screen reader users will be unaware of the feedback message 

Expected Result

The screen reader should make an announcement when users submit the form successfully.

The success message that is visible on a page should be announced when the user submits the form.

1. To make an announcement for a success message add role="status" to the element that contains the visible status message i.e., “Thank you for your feedback!)”.
2. The aria-live region role of status has an implicit aria-live value of polite, which allows a user to be notified via screen reader when success messages are added/displayed on the page.
3. Additionally, the role of status also has a default aria-atomic value of true, so that updates to the container marked with a role of status will result in the AT presenting the entire contents of the container to the use

Code snippet

<div role="status" aria-live="polite" aria-atomic="true" class="aui-message aui-message-success">
<p class="title"><strong>Thank you for your feedback!</strong></p>
<p>Thanks for providing your feedback! This window will automatically close in 5 seconds.</p>
</div> 

Workaround

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