mask not working inside web-component

[artvel]

Hi @NepipenkoIgor,

I've opened this issue because this mask does not work inside web-component(s). But it is not as bad as it looks like as I already know the cause of the issue.

document.activeElement doesn't behave as usual when using web-components. A loop is necessary to reach the target element.

function docGetActiveElement(){
 let el;
 let target = document;
 while(el = target.activeElement){
  if(el.shadowRoot){
     target = el.shadowRoot;
  } else {
    break;
  }
  return el;
}

Implementing this solution does not break the mask when using it without web-components.

I saw the open PR, but it breaks things and it is pending since last year. Maybe this finds a faster way to a valid release :-)

Hope it helps. Cheers
