The dashboard profile menu submenus (Help & Learning, Community &
Contributions, About Penpot) opened on pointer enter but nothing closed
them when the pointer left the option, leaving a stale submenu visible
until the whole menu closed.
Close the open submenu when the pointer leaves an expandable option or
its submenu, with a 200ms grace period (same approach as the workspace
context menu) so the submenu survives the pointer crossing the gap
between the parent menu and the floating submenu. Keyboard navigation
is unchanged and now covered by tests.
