Dealing with focus and blur in a composite widget in React

A pen from codepen.io that illustrates the order in which keydown, blur, focus and keyup events fire for a tab traversal. It also illustrates the target of each event.
A GitHub Gist illustrating a very simple React Component for a grid element that responds to blur and focus events.
  1. Toggle isManagingFocus to true when an element inside the grid gains focus
  2. Maintain isManagingFocus as true as long as an element inside the grid has focus
  3. Toggle isManagingFocus to false when no element inside the grid has focus.
