Incorrectly Displayed Buttons on the Course Management Page

If we decrease the width of the screen, the buttons on the Course Management page seem to be displayed incorrectly.

*Note: the Course Management page can be accessed by expanding the "Admin" accordion on the sidebar.*

Open the Course Management page by expanding the Admin accordion in the sidebar and reproduce the button layout at narrower screen widths. Inspect the page's frontend entry point and compare the two supplied screenshots; done means the buttons remain correctly arranged and usable across the shown widths.
