Description
Describe the bug
The problem is duplication of cookies, which causes an endless Redirect. There are two CookieContainer. One is added to the RestClient.CookieContainer, along with the main cookies, and the second stores the cookies received when processing the Redirect or after the request is completed, according to this decision 2045#issuecomment-1500095598. The problem is that the first and second CookieContainer are added in turn to the request, which causes duplication.
var containerRequest = new CookieContainer();
var containerResponse = new CookieContainer();
var client = new RestClient(new RestClientOptions()
{
AutomaticDecompression = DecompressionMethods.All,
FollowRedirects = true,
MaxRedirects = 10,

Additional context
At first I had one CookieContainer in RestClient and HttpClientHandler, but one of the users complained that he was always getting errors. When browsing through the http debugger, I found out that the cookies were duplicated, i.e. in the beginning there were cookies that were before the request, and then there were updated cookies, although the CookieContainer contained updated cookies.
Then I thought to put cookies only in HttpClientHandler, but with Redirect they were reset and it turned out that I was not authorized, if I put cookies only in RestClient.CookieContainer, then I will not receive cookies from the request and they will not be updated with Redirect.
