如何在Flex Canvas触发子元素上停止Mouse Out事件

.child-element {
  pointer-events: none;
}

const childElement = document.querySelector('.child-element');

childElement.addEventListener('mouseover', (event) => {
  event.stopPropagation();
});

childElement.addEventListener('mouseout', (event) => {
  event.stopPropagation();
});
