Nothing in the failure log looks like it's plausibly caused by these changes. Sometimes things accidentally break on master and a rebase is required for a PR to get out of the bad state. Can you rebase and force push this?

It's odd that these tests aren't in css/css-overflow/, but this seems right. I'll edit the patterns a bit though since the files are all scroll-behavior-*.

Anyone have any idea why this PR keeps failing the wpt-decision-task ? https://github.com/web-platform-tests/wpt/pull/56467/checks?check_run_id=57199559120

@gnarf At first, I thought it was simply flaky. I tried it three more times, but it failed consistently. Then, I thought that it might be based on a faulty commit in the main development branch, but it failed after merging in the latest revision.

My latest theory is that it's somehow balking at permissions (either in GitHub or in TaskCluster) for your account. That's why I squashed, rebased, and submitted a new pull request with a single commit that lists you as the committer and me as the author.

That actually works. I'm not in a position to investigate TaskCluster any more deeply, so I'm going to merge that pull request, close this one, and move on.

Thanks @gnarf and @foolip!
