cubicweb #1218926 small images can get redimensionned to 1px in some views [open]

On a forge intance I attached to a ticket a small image (bullet_orange.png from the cw sources). The file view of that image has the img redimensioned to 1px wide (and auto height), which makes it invisible on screen. Imo, redimensioning is fine, but it should not happen if the original image is below a given size.

SThénault says he thinks the culprit could be cubicweb.image.js
