I was unable to reproduce the text failure on macOS Sequoia arm64 Release ToT using the following command:

run-webkit-tests imported/w3c/web-platform-tests/event-timing/retrievability.html --5000 -f

[Bryan Medina]

It seems to me that the regression point is at 298573@main, since that is where the test started failing and when changes were made to event timing.
