Focus info popup appearing blank

[akarki2005]

Proposed Changes

This change fixes a bug (issue #1573) causing the focus info popup to be blank.

Before

Currently, clicking on a focus tab does not highlight the relevant courses as it should.

Also, the info popup for each focus is missing the focus description.

After

Now, clicking on a focus tab correctly highlights the relevant courses for the focus.

Additionally, the info popup displays information about the focus.
