Odd Menu bar click behaviour

Using website on Firefox - also tested on Chromium.

When you hover over one of the menu items, Discover, Import etc. the dropdown pops up. If you click, it takes you to that page, if you don’t move your mouse and click again, the menu bar doesn’t come back up. You have to go off it and back on to it for the dropdown to reappear.

The most inconvenient interruption this causes is over the User menu - the dropdown is genuinely useful, it would be more user friendly if clicking again brought back the dropdown.
