            Bug ID: 275467
           Summary: The preconnect to an HTTP/1.1 origin blocks a main
                    resource request.
           Product: WebKit
           Version: Other
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: Normal

         Component: WPE WebKit
          Assignee: webkit-unassigned at lists.webkit.org

The preconnect to an HTTP/1.1 origin blocks a main resource request in the following case:
Step: 
1. Load an HTTP/1.1 origin.
2. Set "window.location.href = current_url;"
3. The above operations was done in 3 seconds in my test.
4. The preconnection at the step 1 blocked the new request at step 2 until preconnection timed out, actually the origin is accessible.
