Does tqdm print properly with --log-output?

🐛 Bug

Not sure if it's a bug or it's expected. When I use tqdm in notebook and use the --log-output option, the progress bar keeps printing to a new line. Anyone having the same problem?

Notebook cell

from time import sleep
from tqdm import tqdm
 
for i in tqdm(range(int(5)), leave=True):
    sleep(0.1)

CMD

papermill papermill-test.ipynb papermill-test-out.ipynb --log-output

Output

Input Notebook:  papermill-test.ipynb
Output Notebook: papermill-test-out.ipynb
Executing notebook with kernel: python3

Same probelm here, would be really nice if this could be fixed!

Something that can be guessed from the shown output, but I also noticed: It even seems like the line is alreadyy updated, but then a new line is printed, so you end up with one line for each step, and an extra one for the current step.
