When using a logging.Filter, it seems to be not working when inside the logging_redirect_tqdm context manager. Here is an example:

import logging

from tqdm.contrib.logging import logging_redirect_tqdm


class Filter(logging.Filter):
    def filter(self, record):
        record.msg = f"{record.msg} -- filter"
        return True


filter = Filter()
handler = logging.StreamHandler()
handler.addFilter(filter)
logging.basicConfig(handlers=[handler])

logger = logging.getLogger("main")

logger.error("outside redirect")

with logging_redirect_tqdm():
    logger.error("inside redirect")

Expected output

ERROR:main:outside redirect -- filter
ERROR:main:inside redirect -- filter

Actual output

ERROR:main:outside redirect -- filter
ERROR:main:inside redirect

It looks like they just ought to be copied over from the original handler. If you like I can prepare a pull request.
