## InjectJsCallback

### Description
This callback is invoked when the document element has been created, allowing for the injection of custom JavaScript or Java objects into the frame before scripts are executed.

### Usage
Implement the callback and register it with the browser instance. Use the `executeJavaScript` method on the frame to interact with the window object.

### Example
```java
browser.set(InjectJsCallback.class, params -> {
    JsObject window = params.frame().executeJavaScript("window");
    if (window != null) {
        window.putProperty("java", new JavaObject());
    }
    return InjectJsCallback.Response.proceed();
});
```

### Important Notes
- Avoid modifying the DOM tree within this callback.
- Do not use Fuzio DOM API to remove the frame, as this will crash the render process.
- The engine is blocked until the callback returns.
