Log statements are not grouped to parent request in App Engine Standard P3 #110

Environment details

• OS type and version: App Engine Python 3 Standard

Steps to reproduce

1. Add couple of logging statements
2. Go to Logs Explorer on your cloud console

Code example

import google.cloud.logging
import logging

client = google.cloud.logging.Client()

client.get_default_handler()
client.setup_logging()

logging.info("Testing lines")
logging.info("Again!")

Result:

As you can see every statement is on it's own line, as opposed to what's expected - the statements should be grouped under one log like in App Engine Standard Python2

How to group the statements to the parent request?
