+ <summary>

+ Whether a page load completed after the app entered the background. We log a

+ 'false' value for each PageLoadTracker that is active when the app enters

+ the background, and a 'true' value for each of those PageLoadTrackers that

+ successfully runs its destructor. This helps to understand how many trackers

+ are destroyed while the app is in the background before they are able to run

+ their destructor. This metric is only intended to help in understanding how

+ often app background leads to data loss, and will be deprecated in a

+ subsequent release. Please contact bmcquade@chromium.org before using this

+ metric.
