Problem from CONF-24596 seems to continue.

You can assign the user by clicking the blank area but it doesn't seem to stick. I've tried everything I can think of to make this work. It just doesn't work.

Steps to reproduce:

1. Select a page and switch to edit mode.
2. Click Insert > Other Macros
3. Search for TaskList
4. Add a TaskList macro and save the page
5. View the page and add a task to the task list.
6. Expand the task to see the current assignee.
7. Click the single person icon to get the user search.
8. Enter part of a user name (Steve) and click Search
9. From the results, check one of the users and click "Select User(s)"
10. Refresh page and its gone

Workaround

If you hit Enter while typing the user, it apparently works.
