[🐛 Bug]: When starting chromedriver with add_argument(f"--load-extension={extension_load}") - BIDI connection make Page.* commands unavailable

[HermesNWO]

What happened?

When starting chromedriver with the load-extension argument, BiDi connection won't makes the Page.* commands available/working.

Below easy step to reproduce

How can we reproduce the issue?

... driver loads
driver_options.add_argument(f"--load-extension={extension_load}")
... driver start no headless

async with self.driver.bidi_connection() as connection:
    self.cdp_bidi_main_session, self.cdp_bidi_main_devtools, self.cdp_cdp = connection.session, connection.devtools, connection.cdp
    await self.cdp_bidi_main_session.execute(self.cdp_bidi_main_devtools.page.enable())

Was this working before, or are you trying this for the first time? I believe our BiDi support in Python needs work.

@AutomatedTester do you know if this should be working?

[HermesNWO]

I have also tried with Selenium 4.16.0 and Chromedriver 122 and then updated to see if any chance of work but nothing... And this is the first time I implement BIDI for Target. related, and it doesn't work... For others like Network. it also doesn't work and don't start.

[HermesNWO]

Actually with my different tries, it happen only with this extension : https://chromewebstore.google.com/detail/i-still-dont-care-about-c/edibdbjcniadpccecjdfdjjppcpchdlm, for the others it works.

[diemol]

It seems to be an issue with the extension, as mentioned in the extension reviews.

I will close this as the root cause is outside Selenium.

[HermesNWO]

No this is a real issue, for example it also stop working with this extensions : https://chromewebstore.google.com/detail/ember-inspector/bmdblncegkenkacieihfhpjfppoconhi

Okay I have found the solution : after reading cdps logs, we can see that the initial BiDi session is using the first target found in the list to make a general session. Indeed we don't want to attach to the first but the last element of the list :

Modify async def bidi_connection(self): in webdriver.py and use -1 instead of 0
