the first attributes of JSON string is misplaced

[AmirHMousavi]

• Reading a JSON file from given path. The pretty version created always the first standalone attributes/members of the JSON are moved to the end.
  for human readability, and in my project, it is very important that every thing be at its original location.
• code used form samples given in the doc

std::ifstream i(R"(C:\file.json)");
json j;
i >> j;
std::ofstream o(R"(C:\pretty.json)");
o << std::setw(4) << j << std::endl;

• the input JSON file looks like (an uglified version)

{"releaseVersion": "0.3.0","toolVersion": "11.0.1","ecus": [{"1":"2"},{"and 100 arrays and onjects"}],"params":[{" 200 arrays and objects here"}] 

• the outputed JSON file looks like

{
    "ecus":  [
        {
        }
     ],
     "params": [
     ],
     "releaseVersion":"0.3.0",
     "toolVersion":"11.0.1"
}

• What is the expected behavior?

• And what is the actual behavior instead?

• Which compiler and operating system are you using? Is it a supported compiler?

• I am using the single_include version downloaded the json.hpp and put it as a header in the project directory and adding it to the source code by #include "json.hpp" and afterwards, using json=nlohmann::json;

• no compilation error.

See the last note at https://github.com/nlohmann/json#notes. The library does not preserve the order of object keys, as it is not required by the standard.
