Summary:
The iOS Maestro
sectionlist-viewabilityflow is repeatedly failing on main when it waits forCheesecakeinoutput, for example https://github.com/react/react-native/actions/runs/40321872438. The test currently stops scrolling once 50% of the item is visible, while the RNTester example setsviewAreaCoveragePercentThreshold: 100. Require full item visibility before asserting that the example reported it. Remove the redundant centering requirement so the scroll can stop at the visibility condition.This is a targeted test-stability hypothesis; the draft PR CI must confirm it on the iOS simulator. If the 100% condition cannot be reached reliably, the PR should not be merged as-is.
Changelog:
[INTERNAL] [FIXED] - Align the SectionList viewability flow with the example visibility threshold.
Test Plan:
yarn prettier --check packages/rn-tester/.maestro/sectionlist-viewability.yml— passed.git diff --check— passed.
