Steps to reproduce:

1. Enable workflow for any asset (e.g. Message Boards)
2. Add MB thread and submit for publication
3. Go to My Workflow Tasks > Assigned to My Roles
4. Click on asset you added
5. Click on the ellipsis and "Assign to Me"

Expected results: Comment box displays, and workflow task is assigned to user
Actual results: Review page displays on modal instead of the comment box. Workflow task remains unassigned. There is no way to assign a task to yourself or to any other user as this is also reproducible when you click on "Assign to"

Reproduced on:
Tomcat 9.0.17 + MySQL 5.7
