PDF file with CalRGB colorspace renders blank

[Snuffleupagus]

The PDF file available at: http://pdf.yt/d/eMEhGsydpLZzY0NR/embed (from #5268) renders completely blank in the latest version (1.0.738) of PDF.js. The following is printed in the console:

"PDF e56ae3f04174a54750e7716e887efa3c [1.4 iTextSharp 5.1.2 (c) 1T3XT BVBA / -] (PDF.js: 1.0.738)" viewer.js:1149
"Warning: Unable to decode image: TypeError: this.colorSpace.fillRgb is not a function" util.js:204
"Warning: Dependent image isn't ready yet" util.js:204

This is a regression from PR #5165, and the obvious issue here is that colorspace.js#L1096 should read:

fillRgb: ColorSpace.prototype.fillRgb,

However, even with that addressed, the file still renders incorrectly:
