Screen cast of the sequence

1. On the file page for a video on Wikimedia Commons I choose to see the menu for the video. 
2. I then click "Use this file" which uses an overlay over the entire screen.
This is placed beneath the menu but over the close button which makes it impossible to get back to the normal view with the mouse (it is possible by clicking Escape) because I cannot click the "x" in the corner of the dialouge and neither click the close on the video menu.
