WebDriver::Session::waitForNavigationToComplete relies on Automation.json's waitForNavigationToComplete returning either WindowNotFound or FrameNotFound to update its internal state. After 306469@main, it now returns WindowNotFound also for non-existent frames. This causes WebDriver::Session to think that the whole window was closed, breaking ~40 tests, mostly "test_no_browsing_context" variants. Tentative patch incoming.
