Bug 1692571 [wpt PR 27615] - Let OverflowClip instead of ScrollTranslation create layout shift root, a=testonly
Automatic update from web-platform-tests
Let OverflowClip instead of ScrollTranslation create layout shift root
This avoids layout shift root status change (causing layout shifts in
descendants ignored) when the existence of ScrollTranslation changes,
e.g. when overflowing status changes or scroll offset changes from 0 to
non-zero.
Summary of layout_shift.cluster_telemetry
https://ct.skia.org/results/cluster-telemetry/tasks/chromium_perf_runs/wangxianzhu-ChromiumPerf-5625/html/index.html:
mainFrameCumulativeLayoutShift 1.441%
