Automatic update from web-platform-tests Fix new-content-transform-position-fixed.html to pass with colored scrollbars (#55523) Add lightpink background to root element so macOS Tahoe scrollbar heuristic picks up lightpink instead of white as scrollbar background. Red box-shadow is added on the root to distinguish it from the `::view-transition` pseudo-element. -- wpt-commits: c4d24fa4abeb2cc01b58535cbaeec876eb9be368 wpt-pr: 55523
