What happens when you close the modal on tabindex?
If the user presses Esc, close the modal.

The first and last focusable elements will act as “sentinels” to let you know when to loop focus forward or backward to stay inside the modal. Display the modal window and focus the first focusable element. As the user presses Tab or Shift+Tab, move focus forward or backward, looping at the last or first elements as appropriate.
