-// the same scope as the method itself. This includes:
-// + Merge popular suggestions with personal suggestions.
-// + Order the suggestions correctly based on the previous ordering.
-// More importantly things out of the scope of testing presently:
-// - Removing blacklisted suggestions.
-// - Storing the current suggestion ordering.
-// - Retrieving the previous ordering.
-// - Correct Host extraction from the URL.
-// - Ensuring personal suggestions are not duplicated in popular suggestions.
