To reproduce the issue, you can use this test app https://drive.google.com/open?id=1kLmMCyuVI9yWviaUL8ma9XgrETl_eBXX
You have to click Toggle admin and then set a pac file url in order to reproduce the issue. Any public proxy can be used to reproduce the issue.

Asking :nhi for advice on this bug - maybe this is something we want to fix in our networking code?
