Bug: incompatibility with standard lib

[bfreis]

According to the docs, it's possible to get 100% compatibility with the standard lib:

100% compatibility with standard lib

Replace

import "encoding/json"
json.Marshal(&data)

with

import jsoniter "github.com/json-iterator/go"

var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Marshal(&data)

I found a case in which this doesn't happen: https://go.dev/play/p/fSAa6wRtDKA

The key piece of the above playground is that, if a struct type has a method MarshalJSON with a pointer receiver, and if there's a field of of a struct with the non-pointer type, the behavior diverge: the stdlib's encoding/json doesn't call MarshalJSON, but Jsoniter does. In the playground linked above, this is shown on the serialization of the field BarNoPtr.

Now, I'm not claiming that Jsoniter's behavior is incorrect (I think it's reasonable behavior; in the very least, it's much more consistent than stdlib's behavior, as the full playground shows). The issue I'm bringing up is specifically the claim of 100% compatibility when using jsoniter.ConfigCompatibleWithStandardLibrary.
