Repro:
On some websites such as msn news, fox news websites, window load events will be triggered multiple times.
This won't happen on Android webview or other browsers

sample website: https://www.foxnews.com/politics/trump-says-he-will-leave-office-electoral-college-votes-biden

Code
window.addEventListener("load", (event) => {
        console.log("load event triggered");
        
    });
