Committed 258116@main (56aa37f2fb91): <https://commits.webkit.org/258116@main> Reviewed commits have been landed. Closing PR #7879 and removing active labels.
It appears that this commit broke the following two API tests for iOS: TestWebKitAPI.WebAuthenticationPanel.GetAssertionCrossPlatform TestWebKitAPI.WebAuthenticationPanel.GetAssertionSPITimeout HISTORY: https://results.webkit.org/?suite=api-tests&suite=api-tests&test=TestWebKitAPI.WebAuthenticationPanel.GetAssertionCrossPlatform&test=TestWebKitAPI.WebAuthenticationPanel.GetAssertionSPITimeout I have confirmed that the regression point was 258116@main because the tests fail at that commit, but pass at the commit directly before it.
