test(browser): retry lost popover clicks and raise the per-test timeout

[matej21]

Makes the Browser Tests job green again — all three CI checks pass on this branch. Two test-only commits cherry-picked from experiment/selection-compiler (PR #69) with their original authorship — they will drop out of that branch on its next rebase — plus a timeout fix that turned out to be the actual root cause.

The failure

Since 2026-07-22 the same two tests have failed in CI on every branch, including main. Both drive a popover: open, type to filter, click the first option.

What it is not

• Not a product regression from the recent merges. Both parents of the merge that first showed it were green, and that merge added only an editor paste fix and its test.
• Not the unpinned agent-browser upgrade, which was the first hypothesis and looked damning: CI installs it with a bare bun add -g agent-browser, which went 0.31.1 → 0.32.x right around the date the failures start. But on a pristine main locally both tests pass on 0.27.1 and 0.34.0 alike, and the full suite is 66/66. Pinning would have fixed nothing.

The actual root cause

bunfig.toml declares timeout = 15000, and bun ignores that key. Verified directly: a test that sleeps 6s is killed at 5002ms regardless of the value. So the per-test timeout is bun's 5000ms default.

clickUntil retries a lost click up to 3 times with a 3s settle each — a budget of up to 12s for one test. It therefore cannot complete a second retry inside a 5s test: bun kills it mid-attempt, and the assertion reports whatever slice of its own budget was left. That is exactly the CI log's

error: waitFor timed out after 3183ms: () => !el("author-select-save-button").isDisabled
(fail) Article with Author Select > changing author enables save [16287.65ms]

— a waitFor that asked for 10s and got 3.2s, inside a test that had already spent its ceiling retrying.

Locally the first click lands immediately, so the retry budget is never spent and the ceiling is never reached. That is why this reproduced only on a loaded CI runner, where the browser suite shares a container with postgres, an S3 stand-in and the Contember engine.

The fix

1. wait for the filtered option before clicking, rather than for any button in the dialog — the old selector could match a row from the pre-filter list that is about to be replaced;
2. clickUntil helper in tests/browser/browser.ts — retries the click until an observable effect appears;
3. --timeout 30000 on the test:browser script, so the retry budget fits, with a note in bunfig.toml recording that its timeout key is inert so the next person does not trust it;
4. pin agent-browser to 0.32.4 in the workflow.

No assertion is weakened; the tests still fail if the app stops working.

On the pin — a correction

An earlier revision of this description argued that pinning would be "cargo-culting a fix for a disproven cause", because locally the suite passes on 0.27.1, 0.32.4 and 0.34.0 alike. That conclusion was drawn from the one environment that cannot discriminate.

The CI record can: it went green on 2026-07-22 with clickUntil and 0.32.4, and Article with Author Select still failed with clickUntil against 0.34.0 — twice, plus once more after the timeout fix. So the driver version is load-bearing for that test, and the bare bun add -g agent-browser meant it could change under the suite between two runs of the same commit (0.31.1 early July → 0.32.x mid-July → 0.34.0 since 2026-08-10).

Moving the pin forward is now a deliberate change that has to carry its own CI evidence.

Verification

Locally 66/66. On CI: 66/66, all three checks green — which is the only place this ever reproduced. Progression across runs on this branch: 64 pass / 2 fail → 65 / 1 (clickUntil + timeout) → 66 / 0 (pin).

Note the other half of what was blocking a green suite is a genuine product bug, fixed separately in #76: an embedded has-many was not materialized before isDirty was read or a mutation applied, which is why packages/bindx-form/tests/formRelations.test.tsx was failing on main.

Follow-up worth a separate issue

bun add -g agent-browser is unpinned, so the browser driver can change under the suite between two runs of the same commit. A reproducibility problem regardless of this bug, and not bundled here.
