Chrome Version: (#62.0.3202.29)
OS: (Windows 7, Windows 10)

What steps will reproduce the problem?
(1) Enabled default search provider policy
(2) Enabled the search provided url as  '{google:baseURL}search?q={searchTerms}&{google:RLZ}{google:originalQueryForSuggestion}{google:assistedQueryStats}{google:searchFieldtrialParameter}{google:searchClient}{google:sourceId}{google:instantExtendedEnabledParameter}ie={inputEncoding}'.

(3) Updated the policy in both server and Client using gpupdate /force
(4) In the client machine, confirmed the policy is updated in chrome://policy and chrome://settings


What is the expected result?
When i type something in the omnibox, it should provide the search results from google.com

What happens instead?
When i type something in the omnibox, it is not showing any results.

Attaching the screen-cast for reference.

Note: Seeing the same behavior on stable #61.0.3163.100, previous Dev #63.0.3213.3 and also on earlier build M58-58.0.3029.110
