Description cvazac 2018-12-21 21:22:18 PST
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
