320518@main added a new internal Automation error type, "StaleNode". This can be raised by AutomationSessionProxy.js::_nodeForIdentifier, but the wrapper nodeForIdentifier swallows all errors, returning only null. This in turn surfaces as a "no such element" instead of the expected "stale element reference". This is causing regressions in the following tests: imported/w3c/webdriver/tests/classic/get_computed_label/get.py::test_stale_element_reference[top_context] imported/w3c/webdriver/tests/classic/get_computed_label/get.py::test_stale_element_reference[child_context] imported/w3c/webdriver/tests/classic/get_computed_role/get.py::test_stale_element_reference[top_context] imported/w3c/webdriver/tests/classic/get_computed_role/get.py::test_stale_element_reference[child_context] imported/w3c/webdriver/tests/classic/get_element_rect/get.py::test_stale_element_reference[top_context] imported/w3c/webdriver/tests/classic/get_element_rect/get.py::test_stale_element_reference[child_context] imported/w3c/webdriver/tests/classic/perform_actions/pointer_mouse.py::test_stale_element_reference[top_context] imported/w3c/webdriver/tests/classic/perform_actions/pointer_mouse.py::test_stale_element_reference[child_context] imported/w3c/webdriver/tests/classic/perform_actions/pointer_pen.py::test_stale_element_reference[top_context] imported/w3c/webdriver/tests/classic/perform_actions/pointer_pen.py::test_stale_element_reference[child_context] imported/w3c/webdriver/tests/classic/perform_actions/pointer_touch.py::test_stale_element_reference[top_context] imported/w3c/webdriver/tests/classic/perform_actions/pointer_touch.py::test_stale_element_reference[child_context] imported/w3c/webdriver/tests/classic/switch_to_frame/switch_webelement.py::test_frame_id_webelement_stale_element_reference[top_context] imported/w3c/webdriver/tests/classic/switch_to_frame/switch_webelement.py::test_frame_id_webelement_stale_element_reference[child_context] imported/w3c/webdriver/tests/classic/take_element_screenshot/screenshot.py::test_stale_element_reference[top_context] imported/w3c/webdriver/tests/classic/take_element_screenshot/screenshot.py::test_stale_element_reference[child_context]
