4.2: exception when filtering a list of users by typing the enter key

In the admin Center, I created some test users and the some groups. When assigning users in a group, I filtered my users result by "r*" and typed the enter key. An exception is raised in the console and the filter is only activated if you clcik with the mouse on the Search button.
