Steps to reproduce the problem:
In the dev console run:
  var x = [];
  setInterval(() => x.push(new Uint8Array(100000000)), 1000);
2. Record a performance or memory profile

What is the expected behavior?
ArrayBuffer allocations are shown as JSArrayBufferData in heap snapshots, but the allocations do not show up in the memory allocation timeline or Performance tab graphs. They appear in the retained size in the memory allocation timeline, but not in the actual graphs (and nowhere in performance recordings).

What went wrong?
See expected behavior

Did this work before? No
