ok,

In case someone else encounters that problem, I could work around by 
redefining registerImageListeners method:
in onImgLoad, before calling this.popup.updateSize(), I set
this.img.width =  this.img.width;
this.img.height =  this.img.height;
That way, image dimensions are set in contentDiv.innerHTML, and 
getRenderedDimensions computes popup size correctly.
