Issue Details

• Electron Version: 10.1.3
• Operating System: Windows 10
• Last Known Working Electron version: 10.1.2

Expected Behavior

I expect that a BrowserView that's set up to auto resize, will do so

Actual Behavior

No auto-resizing happens

To Reproduce

1. start the app below
2. when the page loads in the browserview, resize the window
3. notice the black background. browser view doesn't resize

main.js:

const { app, BrowserWindow, BrowserView } = require('electron')

async function createWindow() {
  const mainWindow = new BrowserWindow({ backgroundColor: "#000" });
  const view = new BrowserView();
  mainWindow.setBrowserView(view);

  const contentBounds = mainWindow.getContentBounds();
  view.setBounds({ x: 0, y: 0, width: contentBounds.width, height: contentBounds.height });
  view.setAutoResize({ width: true, height: true });

  await view.webContents.loadURL("https://google.com");
}

app.on('ready', createWindow)
