@josepharhar can you help investigate this? This failure might be the difference between Chrome getting an Interop 2022 score of 71 or 72, or at least it's part of the cause for a decrease, together with https://github.com/web-platform-tests/wpt-metadata/pull/2519.

Sorry for the delay, looking at this now: https://bugs.chromium.org/p/chromium/issues/detail?id=1316643
