Properly memoize menu and popover

[oddvernes]

Describe the bug

Menu and popover uses the popper hook which sends updated positional data every frame during scrolling, which means these components and some of their children gets rendered every frame (not painted though, just the function runs which can be a bit heavy on itself)

Steps to reproduce the bug

1. console log the functions and children

Expected behavior

Better memoization to avoid performance impact during scroll. Also perhaps there is a way to pause popper when the popup is closed
