/* Column visibility + column filter dropdowns */

/* The popover is a flex column so a search header can stay PINNED while the
   option list below it scrolls. `max-height` is set inline by
   components/dropdown.js from the space actually available under (or over)
   the anchor — it must not be a fixed value here, or a short list gets a
   pointless scrollbar and a tall one still spills.

   It used to have no max-height at all. With `position: fixed` that meant a
   35-option list (Controls > DB Types, ~1014px) hung ~950px below the fold
   with no way to scroll to it — the page slid underneath and those options
   were unreachable. */
