Steps to reproduce the problem:
1. add listeners to chrome.notifications (see below)
2. generate a notification with chrome.notifications.create() 
3. click the main area /'non-button area' of the notification (see red box in attached image)

// add these
chrome.notifications.onClicked.addListener(notificationId => {
  console.log('notification onClicked')
})

chrome.notifications.onButtonClicked.addListener((notificationId, buttonIndex) => {
  console.log('notification onButtonClicked', buttonIndex)
})

What is the expected behavior?
console prints: 'notification onClicked'

What went wrong?
console prints: 'notification onButtonClicked -1'
