The crash is indeed a flaky one, and not exclusive of that test: imported/w3c/web-platform-tests/fetch/data-urls/base64.any.html crashed with a very similar trace in: - https://build.webkit.org/results/WPE-Linux-64-bit-Release-Tests/304005@main%20(24149)/results.html - https://build.webkit.org/results/GTK-Linux-64-bit-Release-Tests/303945@main%20(22382)/results.html

`imported/w3c/web-platform-tests/close-watcher/user-activation/n-activate-preventDefault.html?CloseWatcher` is also a flaky crash with the same stack trace.
