The regression range is https://commits.webkit.org/compare/268913@main...268941@main . There are no other test run reports on the dashboard between 268941@main and the last consistent passing at 268913@main. Looking at the changes in the regression range, perhaps the changes to the RenderBlockFlow caused this (268934@main?)? I have been unable to reproduce this at this time.
