"file created" confirmation doesn't clear like other notifications

it doesnt clear at all without clicking the x, even navigating to other pages, doing actions which trigger other notifications

Reproduce the "file created" notification and compare its dismissal behavior with other notifications, including navigation and actions that trigger new notifications. Locate the notification implementation by searching for the displayed message, then verify that the notification clears in the same situations as the others without requiring the close control.
