Failure detail (from injected Part 1 data): Assert.True() Failure — Expected: True, Actual: False, raised from Microsoft.AspNetCore.E2ETesting.WaitAssert.True at VirtualizationTest.cs:4835, i.e. the viewport-stability assertion (AssertWindowScrollViewportStaysStable) did not become true within the wait timeout after a prepend-at-top scroll operation. Failed twice over the past 30 days, not a consistent regression (is_consistent_regression is false). This looks like a timing-sensitive assertion around window-scroll anchor-mode virtualization — the DOM/JS side may occasionally need slightly longer to settle after the prepend than the wait-assert timeout allows, similar to other already-quarantined AnchorMode_* virtualization tests in this same class (issues #66970, #68775, #68730, #68644, #68777). Quarantining while the timing is investigated further.

Quarantining via a follow-up PR.
