"Search Courses" detail popup becomes permanent if user changes the page

If you click the Next/Previous page button in Search Courses while you have a popup with course summary open, the popup both stays open and becomes permanent,

MEDG-101 popup from page 1 persists onto page 2, and will no longer close if I click away or open another class's popup.

Popup will persist into "Make a Schedule" and "Browse Courses" page as well
