      Description

      Some of the reports in Moodle contain selects that list every course in the site, for example

      • Statistics Report
      • Log report (after pressing [more] by the course select)

      When a user opens one of these course selects if the Moodle site has many courses it can cause the browser to freeze for an extended period of time making the page completely unresponsive.

      Our Moodle had over 80,000 courses, trying to open the course select on the statistics page in Chrome freezes the Statisics report page for a few minutes while the browser tries to render the contents of the select.
