I was able to bisect the issue to 253530@main running command: run-api-tests TestWebKitAPI.DocumentOrder.Positions Unable to find builds in proximity to 253530@main. I needed to download them similar to the bots to get test results.
This was resolved with a revert in https://commits.webkit.org/253566@main
Oh, man. This was a really silly issue. The test uses a bunch of WebCore functions directly, and it's stumbling upon XMLNames not being initialized.
