Menu scrolling: expanded menus are absolute rather than fixed
To replicate:
- Go to any contact, and then scroll a little way down the page
- Click on 'Contacts' in the main menu
- Then scroll back up the page
- The expanded menu remains lower down the page (see screenshot)
- This was first raised as a Shoreditch theme issue (see here) and then OP realised it was a Civi core bug
