javascript - Need wisdom! Open a child window in new tab, when child closed clicking links do nothing. Worked before opening child

Question

By clicking in an image ( onClick ), I am able to popup a new Child window in Parent tab and either click in the Child window or the viewable area in the Parent and close Child window. Links that worked in the Parent before do not work after opening/closing Child window. Funny thing is that I an open another Child window as above which works.

See for yourself here.

Used javascript on parent:

let win = "";
function showBig(Path,sWw,sWh,nWw,nWh)  {
 var popIt = document.getElementById('Mask').className;
 if (popIt == 'Active' )    {
    document.getElementById('Mask').className = 'Popup';
  var l=((sWw - nWw)/2)
  var t=((sWh - nWh)/2)
  win = window.open('ShowBig.php?'+Path+','+nWw+','+nWh, '_blank','left='+l+',top='+t+',width='+nWw+',height='+nWh+',resizeable=0')
    let bar = document.querySelector("body");
    setTimeout(() => {  bar.addEventListener("click", event => { closeChild(); event.preventDefault();  }, true) }, 500 );
 }
}
function closeChild()       {
    document.querySelector('body').removeEventListener("click",closeChild, true)
    document.getElementById('Mask').className='Active';
    win.close()
}
    
function closeBig(id,Path,I)        {
 document.querySelector('body').removeEventListener("click",closeChild, true)
 document.getElementById('Mask').className='Active'
 window.close()
}
