            Bug ID: 193006
           Summary: infinite resourcetimingbufferfull loop
           Product: WebKit
           Version: Safari 12
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: cvazac at gmail.com

During a `resourcetimingbufferfull` handler, a web-platform-test [0] fetches a resource. Per spec [1] the entry for that resource should land in the secondary buffer ("add a PerformanceResourceTiming entry" step 4) and then ultimately dropped ("fire a buffer full event" step 5). Instead, another `resourcetimingbufferfull` is firing, and we end up in an infinite loop
