Small tweak to fix tooltips and popover menus coming in accidentally. It's good UX to introduce a small delay, which is especially helpful in the top right section where there's multiple ribbons with hover states.
Add 500ms delay to all tippy tooltips
Add 500ms delay to nav items
Treat nav items as singletons, so after 1 delay, moving to other items has no delay
Add 300ms delay on mouse out to prevent accidentally closing the menu.
