  Focus reset happens when an active (currently focused) element, gets removed form the DOM or the render tree. On focus reset, document.activeElement refers to relative top most node; i.e. body or iframe, leading to an unpleasant user experience for keyboard only users and screen reader users.

  To mitigate the focus reset problem, one must implement guided focus management. As the name suggests, in guided focus management, one programmatically focuses the desired HTML element/node.

  For example, when a modal is displayed, the modal container is focused, similarly, when a modal is dismissed, the element that had triggered the modal display, is focused.

  When an HTML element/node is focused, screen reader generally reads out the content of the HTML element, which serves as a feed back to the non sighted users.
