Using reproduction steps above, I found that the tests were passing at 297542@main, but failed at 297543@main. At this time, I believe that the regression point is 297543@main. 2132873 4 bmedina2 2025-07-28 08:11:45 -0700 For context, the test is a constant failure on iPadOS, but a flakey failure on iOS. 2132874 5 ews-feeder 2025-07-28 08:16:32 -0700 Test gardening commit 297927@main (65ee64e9b646): <https://commits.webkit.org/297927@main> Reviewed commits have been landed.
