Detailed steps to reproduce the problem?

This occurs when the user changes the global http.DefaultTransport variable:

package main

import (
	"context"
	"net/http"

	_ "github.com/motemen/go-loghttp/global" // Just this line!
	"go.mongodb.org/mongo-driver/v2/mongo"
)

type nonDefaultTransport struct{}

var _ http.RoundTripper = &nonDefaultTransport{}

func (*nonDefaultTransport) RoundTrip(*http.Request) (*http.Response, error) { return nil, nil }

func main() {
	http.DefaultTransport = &nonDefaultTransport{}

	client, err := mongo.Connect(context.Background())
	if err != nil {
		panic(err)
	}

	defer func() { _ = client.Disconnect(context.Background()) }()
}

Definition of done: what must be done to consider the task complete?

We should not define a global client, create one as needed.
