### Issue Details

* **Electron Version:**
  * 11.0.3
* **Operating System:**
  * Windows 10
* **Last Known Working Electron version:**
  * <!-- (if applicable) e.g. 3.1.0 -->

### Expected Behavior
An invalid entry to the `JumpList` does not cause other entries to disappear.

### Actual Behavior
A single invalid `JumpList` entry makes all other entries disappear.

### To Reproduce

```ts
// Modules to control application life and create native browser window
const { app, BrowserWindow } = require('electron')

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow

function createWindow() {
  // Create the browser window.
  mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true
    }
  })

  // and load the index.html of the app.
  mainWindow.loadFile('index.html')

  // Open the DevTools.
  // mainWindow.webContents.openDevTools()

  // Emitted when the window is closed.
  mainWindow.on('closed', function () {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    mainWindow = null
  })
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow)

app.setJumpList([
  {
    type: "custom",
    name: "Recent Workspaces",
    items: [
      {
        type: "task",
        title: "Title",
        description: "Description",
        program: process.execPath
      },
      {
        type: "task",
        title: "Long Title",
        description: "DescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescriptionDescription",
        program: process.execPath
      }
    ]
  }
])

// Quit when all windows are closed.
app.on('window-all-closed', function () {
  // On OS X it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', function () {
  // On OS X it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (mainWindow === null) {
    createWindow()
  }
})

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.
```

### Additional Information
It looks like this happens when the `description` property exceeds 255 characters length?
