Automatic update from web-platform-tests Fix popover top-layer nesting WPT helper and hints test expectations Fix a few issues with the popover top-layer nesting WPT: - The `data-stay-open-fullscreen` attribute was added but never implemented in https://crrev.com/c/7727959. - User activation can be performed before the test starts, to avoid problems with the user activation `click` triggering light dismiss. - Fixed up expectations around nesting hints inside autos. All of these test cases currently fail across browsers, so this should improve the status quo: https://wpt.fyi/results/html/semantics/popovers/popover-top-layer-nesting-hints.html?label=experimental&label=master&aligned&view=interop&q=label%3Ainterop-2026-dialogs-and-popovers Fixed: 515728342 Change-Id: I342a366a8f90d7541693b09b6f8ceab3c7faa762 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/7988113 Commit-Queue: Joey Arhar <jarhar@chromium.org> Reviewed-by: Joey Arhar <jarhar@chromium.org> Auto-Submit: Mason Freed <masonf@chromium.org> Cr-Commit-Position: refs/heads/main@{#1652452} -- wpt-commits: 366adfdfb5edeff03be1c37d71b00c034cd23eb6 wpt-pr: 60899
