Gradient at wrong angle

[ghost]

Take a look at this document: test.pdf

There are (subtle) gradients in the border of the "key" images (i.e. Alt and F1) and those seem to have the wrong angle in PDF.js (tested in Firefox 43/Linux, with the web viewer).

In Evince, where things look correct, the gradient angle is about -45deg, whereas in PDF.js, the angle seems like it is around -70deg.

Edit Tim is correct, the gradient is only over the border.

I had to zoom to 400% to finally see it, but you're right. It's best seen in the gray border around the keys.
