Steps to Reproduce

1. Open the HIBB Confluence home page.
2. Observe that a “Welcome” modal dialog appears as soon as the page is loaded.
3. Navigate through the dialog content pressing Tab or Shift + Tab keys and observe that the background content receives focus.
4. Listen that the background content is announced as well while navigating with virtual cursor (up and down arrow keys)

Actual Results

Keyboard focus is not restricted in the "Welcome" modal dialog. Hence, focus moves on to the background content when users press Shift + Tab keys from the first interactive element or Tab key from the last interactive element of the modal dialog. Same behaviour is observed when users navigate using virtual cursor (up and down arrow keys) of screen reader as the background content is read out thereby creating a confusing experience for the screen reader and keyboard-only users.

Expected Results

Focus should be restricted in the modal dialog while navigating with a screen reader or keyboard.

Apply the following changes ->

• Use aria-hidden="true" and tabindex="-1" on the background page container to hide background content from screen readers and keyboard-only users while the modal dialog is open.
• Ensure that the aria-hidden and tabindex="-1" attributes are removed from the background container when the user closes the modal dialog.
• Modify the scripts so that Tab and Shift+Tab always wrap focus between the first and last focusable elements inside the modal dialog, keeping keyboard focus trapped within the dialog in all supported browsers.

Workaround

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