The test was failing before that, too. The difference here is in Accept-Language header field, which is very much not something I'd expect. Is this reproducible locally? Could be leaking state from some preceding test. Seems worth investigating. 2035666 4 ews-feeder 2024-05-15 16:41:16 -0700 Test gardening commit 278836@main (1b89fed26859): <https://commits.webkit.org/278836@main> Reviewed commits have been landed.
