Electron Version

19.0.6

What operating system are you using?

Windows

Operating System Version

Windows 10 version 21H2

What arch are you using?

x64

Last Known Working Electron version

No response

Expected Behavior

Low entropy user agent client hints as:
sec-ch-ua
sec-ch-ua-mobile
sec-ch-ua-platform

Should be send on each request, also if not received header "Accept-CH" in the server response

High entropy user agent client hints as:
sec-ch-ua-arch
sec-ch-ua-full-version
sec-ch-ua-full-version-list
sec-ch-ua-platform-version
sec-ch-ua-bitness
sec-ch-ua-wow64

Aren't working at all
Electron never sending those, even after response with "Accept-CH" header

Actual Behavior

After PR #34481 the low entropy hints are working from the second request (after receiving header "Accept-CH" in the server response)
If testing in Chrome Incognito, can see that those headers are always sent in Chrome versions 102/103

The high entropy hints aren't working at all, also after PR #34481

I did test with new BrowserWindow/loadURL to:
https://www.bing.com/search?q=car

In newest Chrome versions the user agent is not include the full browser version
The server can find it only by high entropy hint sec-ch-ua-full-version or sec-ch-ua-full-version-list

Example of http request headers in Chrome 103.0.5060.53

Host: www.google.com

Thanks for reporting this and helping to make Electron better!

Because of time constraints, triaging code with third-party dependencies is usually not feasible for a small team like Electron's.

Would it be possible for you to make a standalone testcase with only the code necessary to reproduce the issue? For example, Electron Fiddle is a great tool for making small test cases and makes it easy to publish your test case to a gist that Electron maintainers can use.

Stand-alone test cases make fixing issues go more smoothly: it ensure everyone's looking at the same issue, it removes all unnecessary variables from the equation, and it can also provide the basis for automated regression tests.

I'm adding the blocked/need-repro label for this reason. After you make a test case, please link to it in a followup comment. This issue will be closed in 10 days if the above is not addressed.
