// The two functions to get the app ID from a WebContents do it in slightly
// different ways and have different use cases.
//
// For example, GetInstanceAppIdForWebContents (used in the shelf and the app
// service instance registry) will filter out app instances running in tabs if
// they are configured to run in a window (current shelf and instance registry
// logic). GetAppIdForWebContents will only report an extension app in a tab
// opened using certain flows (see bug for details).
//
// Eventually they need to be merged, but in the meantime if you need guidance
// on which one you should use, please reach out to alexbn@chromium.org.

// associated.

// - for extension apps: associating the app ID with the WebContents'

//
// If the app is neither an extension or a web app, no ID is set.
