In the context of running this tests/wpt/web-platform-tests/html/browsers/browsing-the-web/unloading-documents/navigation-within-beforeunload.html for #20329, I am getting the below recursion error.

This happens reliably after 66 navigation, while the test seems to expect 1000 to occur without such error happening(the test ends up failing with assert_equals: expected 1000 but got 66).

ERROR:script::dom::bindings::error: Error at http://web-platform.test:8000/html/browsers/browsing-the-web/unloading-documents/navigation-within-beforeunload-1.html?0.6222672494976191:8:3 too much recursion

Any ideas how this could be solved?

Fixed by adding, as par the spec, a recursiveFlag to both document.prompt_to_unload and `document.unload. See
