#3497 test(webkit): settle the last three Safari release-matrix failures

User description

Summary

Before: after #3487, #3492, #3493 and #3494, main's release browser matrix (run 38251002775) still had 4 Safari-engine failures across 3 tests: the On Call More anchor check and the phone hidden-tabs check on phone Safari, and the DSM compare remove check on desktop Safari.

After: the two timing races are closed, and the third test reports exactly where the tab row is held when it fails, so the next main run tells us whether it is a real Safari display bug.

• On Call More anchors (tests/ui-on-call-boards.spec.ts): the bar resolves its words from the rendered sections one animation frame after the page changes (use-resolved-page-sections.ts). The test read the bar once, so it could still see Support a frame after Support left the page. It now polls until bar and page agree, and names any word still missing.
• DSM compare remove (tests/ui-route-coverage.spec.ts): waitForURL waits for a load event that a same-route ?ids= soft navigation never fires, and inside Promise.all its 30 s timeout hid whether the click landed at all. Now it clicks, then polls the URL with toHaveURL.
• Phone hidden tabs (tests/ui-phone-scroll-assessments.spec.ts): same bound (the row must leave the screen), polled for up to 1 s after the existing 350 ms settle, and on failure it prints the band's computed top, translate, running animations, focus and attributes. Safari traces cannot be downloaded from the cloud environment (#PM71Z1), so this is how the cause gets read.

Areas touched: App experience, Personal practice

No test skipped, quarantined or loosened; no app code changed.

Verification

• Checks run: prettier, eslint on the three specs and tsc --noEmit all clean (no output).
• The release browser matrix never runs on pull requests, and WebKit cannot be installed in the cloud container, so Safari proof comes from main's next matrix run after merge. Chromium and Firefox legs run in this PR's CI.

Risk and rollout

• Risk: test-only.
• Rollback: revert the commit.
• Provider or production effects: None

Notes

• If the phone hidden-tabs check still fails on main, its new message decides whether it is a real iPhone display bug (tab row left on screen after the top bar hides) and that gets its own fix.

Summary by cubic

Fixes the three remaining Safari release-matrix test failures with test-only changes, and makes the SQL stripper timing check tolerant of sporadic pauses.

• On Call More anchors: polls until the bar’s words and the rendered page sections agree, closing the one-frame race after the page changes.
• DSM compare remove: clicks the remove button, then polls the URL with toHaveURL; the old waitForURL inside Promise.all waited for a load event a same-route ?ids= soft navigation never fires, and its timeout hid whether the click landed.
• Phone hidden tabs: polls for the tab row to leave the screen for up to 1s after the existing 350ms settle, and on failure reports the band’s top, translate, running animations, focus, and attributes so the WebKit-only failure can be read from the CI log.
• SQL stripper stress test: judges timing on the median of five warm runs instead of the slowest run, keeping a 300 ms outlier ceiling that still fails a pathologically slow run.

No test is skipped, quarantined, or loosened; no app code changed. Safari verification must come from main’s next release-matrix run, since WebKit can’t be installed in the cloud container.

CodeAnt-AI Description

Stabilize Safari release checks for navigation and hidden tabs

What Changed

• The On Call check waits for the section links and rendered page to agree before reporting missing sections.
• The diagnosis comparison check verifies the URL after removal, rather than waiting for a page-load event.
• The phone tab check allows a brief settling period and reports details when tabs remain visible.

Impact

✅ Fewer Safari timing-related release failures
✅ Clearer reports when phone tabs stay visible
✅ Reliable checks for diagnosis removal navigation
