Log messages appearing twice with Python Logging after pio.renderers.default = "notebook"

After importing plotly.io and setting the pio.renderers.default = "notebook" in my Python code, All Log messages appearing twice with Python Logging

python version: 3.9.12
plotly version: 6.1.2

import logging

# create logger
logger = logging.getLogger('simple_example')
logger.setLevel(logging.DEBUG)

# create console handler and set level to debug
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)

# create formatter
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

# add formatter to ch
ch.setFormatter(formatter)

# add ch to logger
logger.addHandler(ch)

## print some message
logger.info("hello test")    #### till this point all looks good

## now import plotly
import plotly.io as pio
pio.renderers.default = "notebook"

## use the logger again , now the same logger.info printing the log message twice
logger.info("hello test after import")

Start by running the issue's Python logging example, especially the import of plotly.io and setting of pio.renderers.default to "notebook". Trace the renderer setup and logging handlers to identify why the second logger.info call is emitted twice; done means the message appears once after notebook renderer selection and the behavior has regression coverage.
