The FT map drew a strip of dead space along the bottom after a zoom.
Leaflet measures its container ONCE, at creation — which for this panel
is the instant the tab is selected, before the flex layout has settled —
and then asks for tiles to fit that stale size for ever. A ResizeObserver
hands it the real size, plus one pass after the first paint for the
layout that settles without ever firing a resize.
And the decode list's continent chips are the seven, fixed. Building
them from the feed meant a row that reshuffled itself every period — a
chip appeared when the first Asian station decoded and moved everything
sideways under the pointer — and it could not say what the filter was
capable of until something had been heard.
