- Replaced the losing Bun.sleep with an unrefed timeout cleared in a finally block.
- Added regression coverage that verifies prompt wheel acknowledgements leave no timer behind.
Fixes#5905
- Released tab.scroll after two seconds when a queued wheel event waits on a busy renderer acknowledgement.
- Preserved immediate dispatch failures and added regression coverage for both outcomes.
Fixes#5905
tab.click/type/fill/waitFor*/scrollIntoView route their selector through
parseAriaRefSelector (.trim) and normalizeSelector (.startsWith) before any
validation, so passing the ElementHandle from tab.id(n)/tab.ref(...) (or an
un-awaited Promise of one) crashed with the opaque minified
"A.trim is not a function" instead of an actionable error.
- Added assertSelectorString guard at both selector funnels; throws a ToolError
naming the recovery ((await tab.id(n)).click() or a string selector) and
distinguishing ElementHandle / Promise / primitive.
- Corrected browser.md: handles are called directly, not fed to tab.click.
- Regression tests in both selector suites.
Fixes#5776
- Implemented cell budget clamping for timeouts to prevent stalled browser operations from exceeding execution limits.
- Added `recover` capabilities for tab workers to clear blocking dialogs and safely terminate hung navigations.
- Introduced `//!world=main` support for `tab.evaluate` via Puppeteer patch to allow execution in main execution contexts.
- Improved failure attribution for tab terminations by tracking dialogs, stalled operations, and specific termination reasons.
- Implemented `waitForSelector` and `waitForNavigation` methods in the browser tool API.
- Introduced per-operation fail-fast budget management with dynamic timeout clamping.
- Added validation for selector engines to reject unsupported Playwright-only platform features.
- Standardized error handling to provide descriptive, named timeouts for stalled browser operations.
