Is there an existing issue for this?

I have searched both open/closed issues, no issue already exists.

CefSharp Version

109.1.110

Operating System

Windows 10

Architecture

x64

.Net Version

.net framework 4.7.2

Implementation

WinForms

Reproduction Steps

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Open New Tab Example</title>
    <script>
        function openNewTab() {
            var newTab = window.open('https://www.etax.chinatax.gov.cn/', 'https://www.etax.chinatax.gov.cn/');
            // window.open('https://www.etax.chinatax.gov.cn/','_self');
        }
    </script>
</head>
<body>
    <button onclick="openNewTab()">点击我打开新标签页</button>
</body>
</html>

Use CefSharp.WinForms.Example，open test.html (code show above )，click the button. you can see the page is nothing.
but if you clear the cookie, and then change test.html code, use window.open('https://www.etax.chinatax.gov.cn/','_self'); instead of var newTab = window.open('https://www.etax.chinatax.gov.cn/', 'https://www.etax.chinatax.gov.cn/');,
the page is load normal.

Expected behavior

load website.

Actual behavior

request return http code 400.

Regression?

No response

Known Workarounds

No response

Does this problem also occur in the CEF Sample Application

Yes using CefSharp.Winforms.Example. But it is normal in cefclient.exe

CefSharp Version

109.1.110

Version is only and unsupported, please don't open new issues unless you can reproduce the problem in the current supported version (M130 at time of writing)

Testing with https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_win_open and everything works fine in M130 using the CefSharp.WinForms.Example.

The file:/// scheme has many security restrictions, should be avoided for anything other then displaying static text in my opinion.

Thank you very much for answering my questions. Following your advice, I tried reproducing the issue again using CefSharp.WinForms.Example, but without success. Eventually, I discovered the original problem: an extra space in "disable-site-isolation-trials" prevented the configuration from working correctly.
Thank you once again for your kind assistance and support; I really appreciate it.
