Navigation Warning Popup Not Appearing During Automation

Question

I am facing an issue when running automation and editing form fields. When I try to leave the page and navigate to another page, the 'Do you want to leave?' popup does not appear. This behavior is expected to warn users about unsaved changes, but it seems to be missing during automation.
Edge version : 132:0:2957.140

Hi @Haseeb zaidi ,

Please note that this behavior is now by design that confirmation dialog (beforeunload event) won't show up when the browser is launched by WebDriver. WebDriver Classic protocol does not support this feature.

As a workaround, you can enable WebDriver BiDi and set unhandledPromptBehavior to "ignore". Based on my test, the confirmation dialog appears as expected.

If you have any feedback on this behavior, please leave a comment in the original Chromium issue post or create a new issue post there. Thanks for your understanding.
