NoScript leaks browser locale if objects are blocked and JavaScript is allowed

If one customizes NoScript in a way that objects are blocked and JavaScript is enabled then the browser locale is leaked even if the user opted in in hiding it. This issue got reported to our HackerOne bug bounty program by ryotak, thanks!
