Create an Agile Board Modal : aria-hidden="true" is used incorrectly.

Issue Summary

For the Create an Agile board modal, aria-hidden="true" is used on informative content making it inaccessible to assistive technology.

Steps to Reproduce

1. In the Jira header, navigate to the Boards link and activate View all boards.
2. In the View all board main content area, navigate to the Create board button and activate it.
3. A modal for Create agile board will appear, in the modal, select either scrum board or Kanban board option.

Actual Results

The "aria-hidden" attribute is provided to the Create an Agile board modal, which becomes available on selecting the Scrum board or Kanban board option from the Create board modal. As a result, screen reader users cannot access the modal effectively.

Expected Results

Remove aria-hidden=”true” from the <div> element in the page source for the modal.

The aria-hidden="true" attribute is used to hide the content from assistive technology users. Although it is a best practice to use the aria-hidden="true" attribute to hide irrelevant content for screen reader users, it can pose issues for screen reader users if it is not used correctly. 
Additionally, ensure the focus does not move out of the modal in the background content unless the modal is closed.

Workaround

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