--- Comment #2 from Fujii Hironori <Hironori.Fujii at sony.com> ---
This issue can be reproduced with MiniBrowser.

1. Start MiniBrowser in a debugger
   devenv -debugexe .\WebKitBuild\Debug\bin64\MiniBrowser.exe --wk1 http://127.0.0.1:8000/css/border-image-loading.html
2. Put a bread point in the error case of CurlRequest::didCompleteTransfer
   https://github.com/WebKit/WebKit/blob/main/Source/WebCore/platform/network/curl/CurlRequest.cpp#L475
3. Invoke run-webkit-httpd as admin
4. Invoke multiple curl commands to stress the httpd
   yes http://127.0.0.1:8000/css/border-image-loading.html | xargs -n 1 -P 16 curl -s -O
5. Repeat clicking 'Reload' button until the break point is hit

'result' was CURLE_COULDNT_CONNECT (0x00000007) in the case.
