Unable to login at gitlab.com with Fedora User Agent extension enabled in Google Chrome

What is/are the relevant URL(s)

Briefly describe the bug

URL redirect loop when trying to login at https://gitlab.com/users/sign_in/.

This is happening because the package fedora-chromium-config changes the User-Agent of Google Chrome and for an unknown reason, the gitlab.com doesn't like that change and keeps redirecting to the same login page over and over.

If possible, please specify how to reproduce the bug

Install Fedora 35 x86_64
Install google-chrome-stable package (e.g.: curl -LO https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm && sudo dnf install ./google-chrome-stable_current_x86_64.rpm)
Install fedora-chromium-config package (e.g.: sudo dnf install fedora-chromium-config)
Open Google Chrome
Go to https://gitlab.com/
Accept all cookies in the banner
Select Login
You'll get stuck at https://gitlab.com/users/sign_in/ with the following message being displayed at every page refresh:

Checking your browser before accessing gitlab.com.

What is your window size, browser, operating system, and versions

Please use the following website to determine your browser specifications and provide a link developers can follow:

What is my browser https://www.whatsmybrowser.org

The User-Agent that works: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.41 Safari/537.36 (https://www.whatsmybrowser.org/b/8ZGXA)
The User-Agent that does not work: Mozilla/5.0 (X11; Fedora; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.41 Safari/537.36 (https://www.whatsmybrowser.org/b/K46W2)

Note that there is an additional Fedora; string in the User-Agent that fails to login.

I'm not sure when this started to fail because I don't login very often in gitlab.com. Once logged in, I spent months without having to login again.

What I can tell is that I use the fedora-chromium-config extension for quite some time (years) and gitlab.com was happy with that. Now, gitlab.com is not happy with that.
