Add another test patch to shade-tensor.in Here, all non-corner control points are where a linear span from the corners would put them, but it's folded onto itself. This defeats a heuristic I was trying locally. PDFium's current approach doesn't draw this path at all (...which is incorrect.) pdf.js does pretty well (but has some minor black pixel artifacts). Preview.app does meh, but it at least paints something.
