Steps to reproduce the problem:
Run chrome via CLI with a proxy server specified and at least one bypassed domain via --proxy-bypass-list

google-chrome --headless --proxy-server=127.0.0.1:9500 --proxy-bypass-list=*.cloudfront.net

What is the expected behavior?
should not intercept requests to a cloudfront domain, but it does in headless mode. If I remove the headless mode flags, the bypass list is correctly honored.

What went wrong?
Requests to the bypasses domain are still being forwarded to the proxy server.

Did this work before? No
