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 [0] https://wpt.fyi/results/resource-timing/buffer-full-add-entries-during-callback-that-drop.html?label=experimental [1] https://w3c.github.io/resource-timing/
