BUG | Dialogue box for hamburger menu on domain won't close in usual way in /manage/directory/domains

[wayneoutthere]

This dialogue box won't close when I click outside of it (as expected in modern environment) and there is no 'x' to close window either so therefore I feel it's a bug report.

Browser = firefox v 132
OS - ubuntu 20.04 (shame on me...)

hope that helps!
