Vivaldi browser recognize as Chrome Browser

[scote]

Here the result I get on Vivaldi Browser with Platform 1.3.4 :

{  
   "description":"Chrome 61.0.3163.91 32-bit on Windows 10 64-bit",
   "layout":"Blink",
   "manufacturer":null,
   "name":"Chrome",
   "prerelease":null,
   "product":null,
   "ua":"Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.91 Safari/537.36 Vivaldi/1.93.955.36",
   "version":"61.0.3163.91",
   "os":{  
      "architecture":64,
      "family":"Windows",
      "version":"10"
   }
}"
