+ <summary>

+ Chrome for iOS crashes in |didCommitNavigation:| if Navigation Manager is

+ empty. It's unclear how the app can get into this state and one assumption

+ is that didStartProvisionalNavigation: does not add a pending navigation.

+ This metric is logged when didStartProvisionalNavigation: fails to add a

+ pending item.
