Why are some handlers not working on the page?

• 0
  Added several handlers on the page window.addEventListener ("load", function () {})
  One of them definitely does not work, perhaps more than one. Is there a limit on the number of listeners?

  There is no limit to the number of listeners.
  
  However, there is stopImmediatePropagation
  
  In the following code, 9 and 10 will not be output to the console.

  window.addEventListener("load", function() { 
  
    console.log(1);
  
  });
  
  window.addEventListener("load", function() {
  
    console.log(2);
  
  });
  
  window.addEventListener("load", function() { 
  
    console.log(3);
  
  });
  
  window.addEventListener("load", function() { 
  
    console.log(4);
  
  });
  
  window.addEventListener("load", function() {
  
    console.log(5);
  
  });
  
  window.addEventListener("load", function() { 
  
    console.log(6);
  
  });
  
  window.addEventListener("load", function() { 
  
    console.log(7);
  
  });
  
  window.addEventListener("load", function(e) {
  
    e.stopImmediatePropagation();
  
    console.log(8);
  
  });
  
  window.addEventListener("load", function() { 
  
    console.log(9);
  
  });
  
  window.addEventListener("load", function() { 
  
    console.log(10)
  
  });
