[🐛 Bug]: Notification popup is treated as window/tab in Edge - headless #14866
Description
What happened?
When we download a file in edge headless, a notification is displayed that file is downloaded. selenium thinks that its a tab. If I check driver.WindowHandles, its considering notification as one more tab, If I try to close the notification using driver.close since I was able to switch to it, its giving some error. Same code works fine in chrome.
If I run test by disabling headless, issue doesn't occur.
Expectation is that download popup should not be considered as a tab/window.
How can we reproduce the issue?
Download latest selenium and install nunit
