When viewing cataloging concern details, the display is missing a space when one changes the assignee without entering update text. To recreate: 1 - enable CatalogConcerns, create a Concern for a bib 2 - on your bib, click Details on your concern 3 - enter text in the Update field, select a user in Change Assignee, click Update 4 - see that your update shows "Private" on the first line, then the new assignee name on the second line 5 - put a user in Change Assignee and click Update button without putting anything in the Update field 6 - see this update shows with "Private[User name]" on one line without a space
