customJS and load window => Dom not fully ready apparently

[foulong]

Hello,

i wish to custom the title, with image ().
I use the option "customJs".

expected :
access title element and modify it

obtained :
impossible to access title element

It seems to dom is not fully loaded.
Below, Js code :

window.addEventListener("load", function () {
    console.log("Window onload event called.");
    /* 
    returns (Q : why "length: 0" ?) :
    .swagger-ui getElementsByClassName 
    HTMLCollection { length: 0 }
    0: <section class="swagger-ui swagger-container" data-reactroot="">​
    1: <div class="swagger-ui">
    length: 2
    */
    console.log(".swagger-ui getElementsByClassName", document.querySelector("#swagger-ui").getElementsByClassName("swagger-ui"));
    /* 
    returns :
    .swagger-ui getElementsByClassName undefined
    */
    console.log(
        ".swagger-ui getElementsByClassName",
        document.querySelector("#swagger-ui").getElementsByClassName("swagger-ui")[0],
    );

    // returns : null
    console.log(document.querySelector("#swagger-ui .info .title"));
});

Thx in advance for your help.

I'm having the same issue.

I'm using customJS in my options.

I can't get any elements using querySelector or getElementBy...
