// MediaAccessHandler for TabCapture API in Public Sessions. This class is
// implemented as a wrapper around TabCaptureAccessHandler. It allows for finer
// access control to the TabCapture manifest permission feature inside of Public
// Sessions.
//
// In Public Sessions, extensions (and apps) are force-installed by admin policy
// so the user does not get a chance to review the permissions for these
// extensions. This is not acceptable from a security/privacy standpoint, so
// when an extension uses the TabCapture API for the first time, we show the
// user a dialog where they can choose whether to allow the extension access to
// the API.
