If we uplift this to 47 we could fix bug 1263154. Want to try that?

Our typical practice for pdf.js bugs has been to try backporting a small self-contained fix instead of a wholesale update. Also, this landed on Fx45, so I'm not sure what we're trying to uplift to 47 here? :) I think bug 1256037 is the one you want.
