Concourse users import summary to be displayed longer

While importing users from CSV file, after "Import" button is clicked, users were imported. However, a small popup appeared with information about some of the users not being included in the import - this popup was displayed for maybe 2 seconds and disappeared, not giving me a chance to check what the error was. I'd suggest to display this popup until it's manually closed, because right now I need to manually check the users list to find out what happened.
