The first failure that I saw on the dashboard for iOS was on 4/7/2022 at r292541, but this does not appear relevant to causing this issue. This test has been flaky for its entire history on the dashboard. The test for Big Sure Debug x86_64 shows on the dashboard, but not on the Layout Test Results, but the bot shows stderr lines.
