The WithSearchBox modal currently has the following accessibility issues:

1. Accidental Scrolling: When the modal content is larger than the viewport, users can accidentally scroll the entire page behind the modal. This disrupts their focus and makes it challenging to interact with the modal content.
2. Focus Loss: When navigating the modal using the keyboard, users might inadvertently tab past the modal boundaries and interact with elements on the underlying page. This behavior is confusing and disrupts the intended interaction with the modal.

Steps to Reproduce:

1. Open the WithSearchBox modal.
2. Attempt to scroll the page when the modal content exceeds the viewport size.
3. Use the Tab key to navigate through the modal elements and observe if the focus moves to elements outside the modal.

Expected Behavior:

1. Scrolling should be restricted to the modal content, preventing any accidental scrolling of the underlying page.
2. Keyboard focus should be locked within the modal, ensuring that users cannot tab to elements outside the modal.

Benefits:

• Enhances user experience by preventing accidental scrolling and focus loss.
• Adheres to accessibility best practices, making the modal more user-friendly for all users, including those relying on keyboard navigation.

Additional Information:

Implementing these changes will significantly improve the accessibility and usability of the WithSearchBox modal. This enhancement aligns with the goal of providing an inclusive and seamless experience for all users.
