Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The change adds regression coverage for virtualizer sizing, but the current fixture does not reflect the expected sizer dimensions, so the test may validate the wrong values. This is a bounded, non-blocking follow-up that should have owner awareness before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (1 warning, 1 inconclusive)

- Around line 2882-2890: Update the test fixture’s three scrollHeight
assignments to include paddingEnd, matching the sizer height produced by
getTotalSize(). In the same fixture, change the initial pinned offset to 130 and
the post-growth height to 400.

Align the fixture with the sizer height. The adapters set the sizer height from getTotalSize(), which includes paddingEnd. Include paddingEnd in all three scrollHeight assignments, set the initial pinned offset to 130, and set the post-growth height to 400.
