sb sometimes gets stuck on wait_for_element

[Hielobro]

sb.refresh()
logging.info("opened my main!")
element = sb.wait_for_element('[data-widget="userAvatar"]', timeout=30)

Hello! Could you please tell me, why sometimes i see in logs that driver refreshed page, but it got stuck forever on waiting for element, and code pauses without raising "element not found" exception after timeout?
What can i do to prevent that? I use pure sb cdp, but if i remember correctly, normal SB has the same issue for me. Its an inconsistent bug

Something on that website isn't loading, but you can change the page_load_strategy when launching the browser to get around that:

pls="none"

Some of the examples use that: https://github.com/search?q=repo%3Aseleniumbase%2FSeleniumBase%20pls%3D%22none%22&type=code

Thanks, but why does it get stuck on wait_for_element, and not on open or refresh? If it is connected to loading strategy. Why timeout does not take its effect?
Also can you be so kind to explain what "pls" does?
Where can i read and choose loading strategies?

There's info on pageLoadStrategy here: https://stackoverflow.com/a/44771628/7058266

I would need to see your full script in order to debug.

it looks something like this. I dont think that this is very reproducable for you, because you need cookies. But when script works for a long time, i see that processes get stuck while doing page loading, or refreshing, or waiting for element. I dont really know how to fix that.
Also i know you will say that docker is bad for using seleniumbase in, but i run the script in container. Website doesnt detect automatisation.
I dont have this issue with old seleniumbase version and old chrome (122)
