This corresoponds with what I am finding by looking through the DOM on
webdraw. The tile is not a superposition of 2 triangles, but 2 triangles
above / below eachother.

?    This is due to an error in the SVG.  In looking at the SVG it
?appears that the pattern consists of a yellow triangle with a pink
?triangle drawn inside of it.  In reality the pattern is a yellow
?triangle with a slightly smaller pink triangle drawn one pattern tile
?height below the yellow triangle (see attached PNG).
?    Thus when we fill the tile drawing left->right, top->bottom.  the
?second row of triangles hides the pink triangle, so no pink triangles
?show up.  If you drew the pink triangle 'above' the yellow triangle it
?would show up.

?    They apparently don't handle overflow=visible so they only draw
?one copy of the graphic in the tile, so the next row doesn't obliterate
?the part of the pink triangle.

?    Hope this helped.
