Except that Dogra empire never won that land, neither ruled or administored over those lands, and was claiming over those lands on the basis of British empire maps which were neither officially recognised between British and Chinese empire of the time & nor demarcated by themselves as Chinese authorities never entertained such requests from British side. Same British empire could not demarcate Sino-British Indian border in east well as British empire accepted the ruling of China over Tibbet and until China & Tibbet both signed the agreement, formal border agreement couldn't be signed. Though athority based in India did sign on agreement with Tibbet, but as per British policy it didn't receive the official backing, neither from British nor from Chinese Authorities. Some food for thought... Thank you.
