When hitting a rule that points to a PAC file, foxy tries to access it directly

* Happening on Chrome Version 119.0.6045.199 (Official Build) (arm64)
* Same issue with v8.2 tag (Checked it out a couple of minutes ago)
* Same issue on the main branch
* If I specify the PAC proxy directly, it works.
* All other SOCK5 proxies are working.
* Happens even if the PAC proxy is the first on the list and it has a catchall pattern.
Not sure how to pull some logs under chrome
