Steps to reproduce - on QA site:

1) Access "Activity examples" course as Teacher - https://qa.moodledemo.net/course/view.php?id=2 .
2) Turn ON the edit mode.
3) Add Activities block
4) In the Assignments topic (https://qa.moodledemo.net/course/view.php?id=2#section-1), change visibility to "Hide from students".
5) In the Activities block click on the 'Assignments" link (to load the page https://qa.moodledemo.net/mod/assign/index.php?id=2 )
6) Verify the appearance of the hidden assignment's link.

Encountered behaviour:

• Link shows as normal - is not dimmed, thus not indicating the "Hidden from students" status

Expected behaviour

• Link should be dimmed to indicate the hidden-from-students state of the assignment (as is the case with all the other activity and resource types listed on the sub-pages linked from the course Activities block.)
