Quarantines a flaky Virtualize component unit test that has failed 3 times in the last 30 days (build 1362201, pipeline 83).

Test

Microsoft.AspNetCore.Components.Virtualization.VirtualizeTest.Virtualize_ScrollToBottom_SetWhenAtEndWithNewMeasurements

The test fails with:

scrollToBottom should either be called via JS interop or be pending

This indicates a timing issue where the scrollToBottom JS interop call is neither made synchronously nor queued as pending when expected, suggesting a race condition in the Virtualize component's scroll-to-bottom logic when new measurements are applied.
