a trick to make web component focusable is:

if (!this.hasAttribute('tabindex')) {
  this.setAttribute('tabindex', 0);

even some elements (like button, input ...) able to set the flag but it's not useful, I need to focus the shadowroot in order to bind keyborard shortcuts

then use document.activeElement to determine whether the component is focused.
