The FilterBar uses overflow-x-auto for horizontal scroll, which forces
overflow-y to auto as well — that was clipping the absolutely-positioned
pill popovers below the bar. Render the popover into document.body via a
portal with fixed coordinates derived from getBoundingClientRect(), and
clamp the left edge so right-most pills don't push the popover off-screen.
