[FR] Implement a safe area for popovers

### Description

Our Popover implementations don't offer the cool triangle-safe-zone-menu-filter thingamabobs that makes navigation user friendly. As a result, all of our sub menus HAVE to be shown until dismissed, instead of hiding as soon as the mouse is out of the safe zone.

### Impact

Any user that opens a nested poover
