Hijack Focus

  1.  
  2. const el = document.body.appendChild(
  3.   document.createElement('div')
  4. );
  5.  
  6. el.innerHTML = `
  7. <button>one</button>
  8. <button>two</button>
  9. <button>three</button>
  10. `;
  11.  
  12. document.addEventListener('click', e => {
  13.   e.target.focus();
  14. });
  15.  
  16. const origFocus = HTMLElement.prototype.focus
  17. HTMLElement.prototype.focus = function() {
  18.   console.log(this.outerHTML, 'focus was called');
  19.   origFocus.call(this);
  20. };
  21.  
  22. el.firstElementChild.focus();

Easy way to debug many calls to focus.
