Fix useClickOutside when the target element is removed

[connor-baer]

Purpose

When an element is clicked inside the container element and removed right after the click, useClickOutside would trigger because, at the time when the hook checks whether the container contains the clicked element, the element has already been detached from the DOM.

Thanks @hris27 for the report and suggested fix! 🙌🏻

Approach and changes

• Check if the container contains the clicked element on the mousedown event. The callback is still triggered on the click event because it can be intercepted, unlike the mousedown event.

Definition of done

• Development completed
• Reviewers assigned
• Unit and integration tests
• Meets minimum browser support
• Meets accessibility requirements
