Add title for tooltip title in other browsers

closes: CNVS-29206

This enables the entire long course title to be seen when you hover over
and view the tooltip.

Test Plan:
- Make sure to have a course with a long name
- Go to All Courses page
- Long course name should truncate, hover over and view tooltip
- Entire course name should appear on tooltip

Should work in all browsers now
