## Summary Fixes an intermittent failure in `tests/e2e/test-map-nodes-pagination-e2e.js`, the "late response after map teardown" cases added for #2030 in #2048: ``` ✗ late /observers response after map teardown: old response must not change the destination page ``` It failed on #2164 ([run 38080812509](https://github.com/Kpa-clawbot/CoreScope/actions/runs/38080812509), shard 2/3), a Go-only change, and passed on the rerun. ## Cause `checkMapTeardown` compares `#app`'s HTML before and after releasing the old map's pending response. When it failed, the only difference was on the destination page's heading: ``` before: <div class="tools-landing"><h2>Tools</h2>… after: <div class="tools-landing"><h2 tabindex="-1">Tools</h2>… ``` That attribute comes from the router, not the old response. Since #630 (`app.js`, "SPA focus management") it focuses the new page's first heading in a `requestAnimationFrame` after the page renders. The before-snapshot was taken as soon as `#leaflet-map` detached, sometimes ahead of that frame. ## Fix The test now waits two frames before the before-snapshot, the same settle it already does before the after-snapshot. The router's frame is queued by then, so it always lands first. The change is test-only: no app code changes, and every assertion stays as it was. ## Tests Run locally with the e2e fixture (`tools/freshen-fixture.sh`, migrated) served by this branch's server, headless Chromium: | | runs | failed | |---|---|---| | test on `master` (`352a0ccd`) | 20 | 2 | | this branch | 50 | 0 | - **Before:** the two failures on `master` were "old response must not change the destination page" (teardown, `/config/regions` and `nodes`), plus one 30 s timeout in an "after map replacement" case in the same runs. - **After:** none of these failures or the timeout came back in 50 runs. ## Checks - **Lint:** ESLint passes with the repo config and with Node globals. SonarQube rules on the file report nothing on the added lines; its four existing minor findings are on lines this PR doesn't touch. - **Repo rules:** one logical change, explicit `git add`, no private data, no new dependencies. This is a test-only fix, so there's no red/green pair: the "red" is the intermittent failure above, measured as 2 in 20.
