I did a few more testing and realized this bug might be related to https://bugzilla.mozilla.org/show_bug.cgi?id=795072 .
Having only a single picture to downscale, as shown in this attachment, makes the HQ scaler work. Having two pictures in an HTML for downscaling, makes the HQ scaler fail.

Note sure if this is the correct bug, but let me add another example:
GOOD: https://github.com/joyent/node/commits/master
BAD: https://github.com/silverwind/Droppy/commits
Github uses downscaled avatar images here, and it seems that if one image appears a certain amount of times, the downscaler doesn't kick in at all for it. In case node's commit log doesnt show smooth downscaling, view any other commit log with many different authors.
In the link here https://bugzilla.mozilla.org/show_bug.cgi?id=486918#c289 (beware, excessive memory-usage!)
some images are scaled, some are not.
So just having more than one image doesn't break the scaling.
