CookieAccessFilter will cause cookie not sent in some requests

[andrewzjl]

• What version of the product are you using?

  • What version are you using? Nuget 86.0.241, 95.7.141, 100.0.23 (latest one)
  • Issue is reproducible for all the CefSharp versions

• What architecture x86 or x64? I tested it in x64, but I think it doesn't matter

• On what operating system?

  • Win7, Win 8, Win10, etc? I tested it in Win 10, but I think it doesn't matter

• Are you using WinForms, WPF or OffScreen? WPF

• What steps will reproduce the problem?

  • Please provide detailed information here, enough for someone else to reproduce your problem.
  1. open the url https://mstra.rjrpub.com/MicroStrategyLibrary/?loginMode=1048576 in cefsharp browser
  2. if the cookie filter is set, it will show an error page
  3. More info is under https://github.com/andrewzjl/CefSharpCookieFilterIssue Same change is done in the forked branch https://github.com/andrewzjl/CefSharp.MinimalExample/tree/CefSharpCookieFilterIssue

• What is the expected output? What do you see instead? It should be the same as the cookieFilter not set, if the cookieFilter.CanSentCookie return true

• Please provide any additional information below.

  • A stack trace if available, any Exception information. No Exception, but the cookie is not sent
  • Does the cef log provide any relevant information? (By default there should be a debug.log file in your bin directory) No
  • Any other background information that's relevant? Are you doing something out of the ordinary? 3rd party controls? I don't know why the cookie is missed, but it happens

You are welcome to review the code, I suspect this is a bug in CEF.

I think adding a unit test or two to validate the wrapper has been implemented correctly is the way to go from a CefSharp point of view. CEF has some tests we can use as a base
