i was testing my extension and i thought everything is fine until i moved my mouse cursor on an ad in stackoverflow and w3school and some other websites! my mousemove event doesnt work on ads. i dont know why. my event handler is:

window.handler = window.handler || function (e) {
  console.log("on");

  document.querySelectorAll(".x_place_ext")[
    document.querySelectorAll(".x_place_ext").length - 1
  ].textContent = e.clientX;

  document.querySelectorAll(".y_place_ext")[
    document.querySelectorAll(".y_place_ext").length - 1
  ].textContent = e.clientY;
};

let positions = document.querySelectorAll("#positions_container_ext");
positions = positions[positions.length - 1];

document
  .querySelector("html")
  .addEventListener("mousemove", window.handler);

i have no idea why these codes dont work on ads in websites. can you halp me?
