RestSharp: AddJsonBody in 107.0.1 does not work properly

I have noticed that AddJsonBody works differently in 107.0.1 version. I am using RestSharp with Pingdom API and have very simple method to pause/resume host.

Here is an example of method in 106.11.7 version

        public IRestResponse ResumeHost(string hostID)
        {
            var request = new RestRequest("checks", DataFormat.Json);
            request.AddJsonBody(new
            {
                checkids = hostID,
                paused = false
            });
            return client.Put(request);
        }

And same code in version 107.0.1

        public async Task<RestResponse> ResumeHostAsync(string hostID)
        {
            var request = new RestRequest("checks") { RequestFormat = DataFormat.Json };
            request.AddJsonBody(new
            {
                checkids = hostID,
                paused = false
            });
            return await client.PutAsync(request);
        }

Second code doesn’t work properly and looks like object was not posted properly.
