// pops up when Chrome offers to save a user's password, or when the user
// interacts with the Omnibox icon. It has two distinct states:
//
// 1. PendingView: Offers the user the possibility of saving credentials.
// 2. ManageView: Displays the current page's saved credentials.
// 3. BlacklistedView: Informs the user that the current page is blacklisted.
