It works for me, with Nightly 145.0a1 (2025-09-30), on Win11.

Updated - I saw the problem as well.

Closing dialog has nothing specific to do with the bug - it just navigates back. The back-navigation itself has a problem.

1. Open any modal popup - like step 3 of comment #0 (but many other ways to do so)
2. You see the new history item is created.
3. Navigate back from the browser chrome

Expected: Back-navigation should only close the popup, as Chrome does
Actual: It causes actual full page navigation.

And the history item is added by the traditonal history.pushState(). Does enabling Navigation API do anything special with the existing History API?

Comment 7

[Kagami Rosylight [:saschanaz] (they/them)]

nsGlobalWindowInner::DispatchSyncPopState is called but only after the navigation happened. Something is causing navigation earlier.

This is potentially just bug 1993239? Google Meets certainly subscribes beforeunload.

https://phabricator.services.mozilla.com/D268124 seemed to fix this.
