Steps to reproduce

1. In Admincentral, log in as a new user for the first time.
2. On seeing the blue modal dialog about data collection, attempt to dismiss it using "enter".

Expected results

1. The dialog, with only one action button, should vanish upon acknowledgement.

Actual results

1. The dialog remains but a red error bar is shown behind it.
2. The red error bar contains no useful information.

Notes

1. As a developer, I encounter this dialog frequently after cleaning and restarting Magnolia.
2. As a user or prospect, this may be my first ever experience of Magnolia. The attached screenshot, for example, comes from the public demo.
