Command line error - "Option 'proxy-server' is unknown. Ignoring."

[astrowonk]

• VSCode Version: 1.39.0
• OS Version: Linux RHEL 7

Steps to Reproduce:

1. Launch code with --no-proxy-server flag
2. "Option 'proxy-server' is unknown. Ignoring." error appears.

I think the proxy is still disabled, the error message is simply wrong? If I run without the flag, I get prompted to log into the proxy, if I run with the flag, the proxy appears disabled (no log in prompting) but the error appears on the command line.

I suggest to include that fix in the recovery builds to avoid any confusion due to the message printed by the cli.
The cli says Option 'xy' is unknown. Ignoring. for all chromium options, but in fact, they are used. My understanding is that most of the chromium options are not for the end-user except --inspect and the proxy settings, so I added these to the list of the valid (supported) args. @joaomoreno @bpasero Please speak up if I missed one of the options.
PR is #82486

This is not fixed in the latest stable release candidate. The reason is that the PR was actually not merged and this issue was closed erroneously
