+    In M57, the values recorded by this histogram were determined to be bugged.
+    It's believed that it was recording uninitialized values due to a corner
+    case on Android that allows an omnibox suggestion to be selected without
+    first focusing the omnibox. In addition to the new histograms,
+    Omnibox.PhysicalWebProvider.SuggestionUsedWithoutOmniboxFocus was added to
+    detect this case. https://crbug.com/691059
