CURLOPT_COOKIEFILE is not dup'ed in curl_easy_duphandle()

[bagder]

I did this

Use (multiple) CURLOPT_COOKIEFILE for an easy handle to load cookies from multiple input files.

Then call curl_easy_duphandle() and run an identical transfer. The cookies are not loaded from the files set to be used in the original handle.

I expected the following

curl_easy_duphandle() is intended to make a "perfect" copy and should then also keep the list of file names to read from.

curl/libcurl version

7.87.0 and all previous versions

operating system

independent
