Page 3 contains many 1-bit images that have /Filter /CCITTFaxDecode and /ImageMask true. The images are supposed to be completely transparent but in PDF.js a black line appears at the bottom of each image. I think there is a bug in the decoder src/core/ccitt.js. The images have also /EncodedByteAlign true, which could be the culprit.
