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")

首先运行 issue 中的 Python logging 示例，尤其要检查 import plotly.io 以及将 pio.renderers.default 设置为 "notebook" 的部分。跟踪 renderer 的设置过程和 logging handler，以确定为什么第二次调用 logger.info 会被输出两次；完成的标准是：选择 notebook renderer 后，消息只出现一次，并且该行为有回归测试覆盖。
