302336 2025-11-11 10:13:28 -0800 [WebDriver][BiDi] Some browsing context events are sending empty context handle field 2025-11-16 15:05:13 -0800 1 1 1 Unclassified WebKit WebDriver WebKit Nightly Build Unspecified Unspecified RESOLVED FIXED InRadar P2 Normal --- 281932 1 lmoura lmoura bburg webkit-bug-importer oldest_to_newest 2157957 0 lmoura 2025-11-11 10:13:28 -0800 Currently, we send some events like `dom_content_loaded` with an empty `context` field. This happens because we use `handleForWebFrameProxy(frame)` for this field, which returns an empty string for frames that happens to be the main frame. This is related to the original scheme from WebDriver classic of keeping track of the top level contexts, etc. For such main frames, the `context` field must have its WebPageProxy's handle (i.e. "page-UUID"), returned through `handleForWebPageProxy(page)`. Patch incoming. 2157958 1 lmoura 2025-11-11 10:15:40 -0800 Example of tests affected: FAILED WebDriverTests/imported/w3c/webdriver/tests/bidi/browsing_context/dom_content_loaded/dom_content_loaded.py::test_subscribe - AssertionError FAILED WebDriverTests/imported/w3c/webdriver/tests/bidi/browsing_context/dom_content_loaded/dom_content_loaded.py::test_timestamp - AssertionError FAILED WebDriverTests/imported/w3c/webdriver/tests/bidi/browsing_context/dom_content_loaded/dom_content_loaded.py::test_early_same_document_navigation - AssertionError FAILED WebDriverTests/imported/w3c/webdriver/tests/bidi/browsing_context/dom_content_loaded/dom_content_loaded.py::test_page_with_base_tag - AssertionError Note that these are currently skipped in `main`, as I'm unskipping/gardening them in bug302107 2157972 2 lmoura 2025-11-11 10:52:06 -0800 Pull request: https://github.com/WebKit/WebKit/pull/53752 2159119 3 ews-feeder 2025-11-16 15:04:48 -0800 Committed 303095@main (6aa3d2c0520d): <https://commits.webkit.org/303095@main> Reviewed commits have been landed.
