Actual Results

The keyboard focus is not restricted within the "Insert SAP ADDRESSBOOK Macro" 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.

This creates a poor experience for keyboard-only users, as it breaks the expected modal interaction pattern.

Expected Results

Ensure that keyboard focus is properly restricted within the modal dialog.

Apply the following changes:

• Prevent focus from moving outside the modal dialog when navigating with the Tab or Shift + Tab keys.
• Ensure that pressing Tab on the last interactive element moves focus to the first interactive element within the modal.
• Ensure that pressing Shift + Tab on the first interactive element moves focus to the last interactive element within the modal.
• Modify the scripts to implement and maintain this focus behavior consistently across all supported browsers.
