LIMITATIONS

Known limitations

- **Shadow DOM / iframe content is not in snapshots**: the walker only covers the regular DOM subtree of the main document; if the page hosts interactive elements inside shadow DOM, use `web_evaluate` or the page's own test hooks (`testid=`). - **ref is a positional path**: see "Snapshot and ref Mechanism" above. - **Popups activate automatically**: new tabs opened via `target=_blank` etc. automatically become the active page (the agent's intuitive click behavior); use `web_tab_list` + `web_tab_switch` to get other tabs back. - The statement-sequence form of `web_evaluate` (multi-statement including function declarations) executes for side effects and returns no value; expression and function forms return results. Use the `async` function form for async logic.
