The D17 floating-pill scroll test (DisplayPage.spec.ts) flaked twice on 2026-07-21 in different worktrees: passes reliably standalone/serial, intermittent under parallel workers (measured 2 pass / 1 fail standalone x3 in one env). Likely an IntersectionObserver/scroll timing race in the test, not the feature (the pill works in every visual verification). Fix the test's wait condition (await the observer callback/pill text change rather than a fixed scroll+assert); do not loosen timeouts blindly. Not release-blocking; annoying in CI retries.
