fix: switch popover back to position:absolute with dynamic max-height

Browse Source 
position:fixed pinned the popover to the viewport layer, so scrolling
the page could never reveal off-screen content. Revert to absolute
positioning (scrolls with the page) and dynamically compute max-height
based on available viewport space so the popover fits and scrolls
internally when content exceeds the available area.
