            Bug ID: 280402
           Summary: WebKitTestRunner dump logic behaves differently in
                    site isolation

          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

WebKitTestRunner dump logic behaves differently in site isolation

Cannot match non-site-isolation if the dump logic is different.

When run after onload, not in onload scope, notifyDone() will dump :
 - no site isolation: *at that moment*
 - site isolation: sometime in the future after exiting the call stack

forceImmediateCompletion() will dump:
 - no site isolation: *at that moment*
 - site isolation: sometime in the future after exiting the call stack


This is due to the fact that dumping needs to traverse the frames. On site isolation, individual frames cannot traverse frames.
