Trying to tile 2 BrowserViews into one BrowserWindow, 1st not rendering

[rkpatel33]

I am running the code below to create two BrowserView's in a single BrowserWindow, one below the other. Each one works independently, however when I instantiate both and add them to the window on the second one remains.

With webview tags this is possible so not sure if this is expected behavior or a bug, seems like a bug.

• Electron version: 1.7.5
• Operating system: MacOS Sierra

Expected behavior

Expect both BrowswerViews to render as long as they are positioned properly (non-overlapping).

Actual behavior

Only the second windowed added shows up.

How to reproduce

main.js file:

const electron = require('electron');
const app = electron.app;
const BrowserWindow = electron.BrowserWindow;
const BrowserView = electron.BrowserView;
const { ipcMain } = require('electron');

const path = require('path');
const url = require('url');

require('electron-debug')({showDevTools: false});

let browserWindow;

function createWindow() {
    browserWindow = new BrowserWindow({ width: 1200, height: 1200 });

    let browserView1 = new BrowserView({
        webPreferences: {
            nodeIntegration: false
        }
    });

    let browserView2 = new BrowserView({
        webPreferences: {
            nodeIntegration: false
        }
    });

    browserWindow.setBrowserView(browserView1);
    browserWindow.setBrowserView(browserView2);

    browserView1.setBounds({ x: 0, y: 0, width: 1200, height: 600 });
    browserView2.setBounds({ x: 0, y: 600, width: 1200, height: 600 });

    browserView1.webContents.loadURL('https://electron.atom.io');
    browserView2.webContents.loadURL('https://www.google.com');

    browserWindow.on('closed', function () {
        browserWindow = null;
    });
}

app.on('ready', createWindow);

app.on('window-all-closed', function () {
    if (process.platform !== 'darwin') {
        app.quit();
    }
});

app.on('activate', function () {
    if (browserWindow === null) {
        createWindow();
    }
});

[enlight]

The current API only allows for one BrowserView per BrowserWindow, multi-view support will hopefully be implemented later.
