            Bug ID: 260667
           Summary: WindowEventLoop can infinite loop trying to run idle
                    callback in suspended pages
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: DOM
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: rniwa at webkit.org

WindowEventLoop::didReachTimeToRun schedules itself again when an idle callback is scheduled but we didn't have enough time to run it.
This logic can infinite loop when the timer never fires because the document has been suspended.
