Hello, when I create a new bar in a notebook without a total, then use the reset method to add a total to the bar, the bar output's as a plain cyan bar that doesn't visually update, however the remaining time and iterations count work well. Step to reproduce in a notebook :

import tqdm.autonotebook as tqdm
bar=tqdm.notebook.tqdm()
bar.reset(10)
for i in range(10):
    sleep(3)
    bar.update(1)

However if I fill the total directly in the class constructor it works well:

import tqdm.autonotebook as tqdm
bar=tqdm.tqdm(total=10)
for i in range(10):
    sleep(3)
    bar.update(1)

Is this a normal behavior ? As I understand the reset method, these two pieces of code should give equivalent result.
