set_browser_env times out when called from a Jupyter notebook

[benber86]

Trying to use set_browser_env in Jupyter will raise a TimeOutError.
Tested on Jupyter 7.2.2 and JupyterLab 4.0.7 (via try.vyperlang.org).
The same issue does not happen on Google Colab

import boa
%load_ext boa.ipython
boa.set_browser_env() 

results in:

TimeoutError: Timeout loading browser browser wallet plug-in.

[DanielSchiavini]

Do you see any errors in the browser console tab? What kind of wallet are you using? Did you get a pop-up at all to connect the site?

[benber86]

no popups at all, tried with both rabby & metamask. windows + chrome, linux + ungoogled chromium
