PDFs from lumileds.com do not load with PDF.js. Part of the background loads, then only the spinner continues while using 100% CPU. 

An example pdf is http://www.lumileds.com/uploads/17/DS61-pdf 

This behaviour occurs with both the release version of pdf.js in firefox 41.0.2 and the latest .xpi downloaded from this github page.

if (!this.contentVisible) {
      return;
    }
    const ctx = this.ctx;
    const w = imgData.width;
    const h = imgData.height;
    const tmpCanvas = this.cachedCanvases.getCanvas("inlineImage", w, h);
    const tmpCtx = tmpCanvas.context;
    putBinaryImageData(tmpCtx, imgData, this.current.transferMaps);
    for (let i = 0, ii = map.length; i < ii; i++) {
      const entry = map[i];
      ctx.save();
      ctx.transform.apply(ctx, entry.transform);
      ctx.scale(1, -1);
      ctx.drawImage(
        tmpCanvas.canvas,
