Anonymous color changes to black.
OP disappears after clicking the toggle
In Discussion forum for InstructorUI, we allow for deanonymouizing the student. When we try to do this, this changes the color to black and the OP that is suppose to be blue is also black for some reason.

Expected behavior

Same as the non-anonymous mode.
OP should not disappear

To Reproduce
Steps to reproduce the behavior:

1. Make a forum post as a student
2. Look at forum post as an instructor
3. Toggle Anonymous mode (eyes)
4. See error
