Qt: Multiple QScrollArea in the same parent widget

Question

I'm using nodegui(QT library for node) and I'm trying to create multiple vertical scroll areas but it doesn't work as expected.

import {QMainWindow, QWidget, FlexLayout,QScrollArea } from '@nodegui/nodegui';
const win = new QMainWindow();
win.setWindowTitle(`Test`);
win.setMinimumSize(900, 600);


const root = new QWidget()

const terminal1 = new QScrollArea()
terminal1.setInlineStyle(`width:100px`)
const div1 = new QWidget()
div1.setInlineStyle('width:1800px; height:100px; border: 1px solid yellow')
terminal1.setWidget(div1)

const terminal2 = new QScrollArea()
terminal2.setInlineStyle(`width:100px`)
const div2 = new QWidget()
div2.setInlineStyle('width:1800px; height:100px; border: 1px solid green')
terminal2.setWidget(div2)

const layout = new FlexLayout()
root.setLayout(layout)

layout.addWidget(terminal1)
layout.addWidget(terminal2)


win.setCentralWidget(root)

win.show();
(global as any).win = win;

Is any way to create stacked QScrollAreas?
