Research direction

Investigate the flaky infinite scroll test in core/src/components/infinite scroll/test/top/infinite scroll.e2e.ts. The issue appears since the Playwright upgrade in PR #29840. Examine the test trace to identify differences in scroll events on Safari vs other browsers. Consider adjusting scroll expectations or using a different scroll method for Safari.
