Videos grid: a clip the player can't load leaves the grid instead of sitting there as a blank tile

A deleted file on Primal's blossom answers 404 without CORS headers, so the
probe saw only a quiet host (not a 404), the server had no still for it, and
the tile's fallback player failed with nothing listening: a blank box (Adam's
iPhone). The player's error now hides the tile and marks the clip gone for a
day, as a 404 the probe could read already did.
