You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: scroll.rs
    path of file: ./repos/TheReader/crates/frontend/src/components/reader/layout
    
    the code of the file until where you have to start completion: use std::{cell::Cell, rc::Rc};

use chrono::Utc;
use wasm_bindgen::{prelude::Closure, JsCast, UnwrapThrowExt};
use web_sys::{Document, HtmlElement, HtmlIFrameElement, MouseEvent, WheelEvent};
use yew::Context;

use crate
    
    pub fn on_stop_viewing(&self, section: &SectionContents) {
        let el: HtmlElement = section
            .get_iframe()
            .content_document()
            .unwrap_throw()
            .scrolling_element()
            .unwrap_throw()
            .unchecked_into();

        el.style().set_property("overflow", "hidden").unwrap_throw();
    }
