This can be fixed by cropping the oversize sprite down to 72x72 (without losing any pixels).
Fixed in commit 964973d567208c18e0d86ea5d4c5ad322ec7217a.

Sprites can't be counted on to be 72x72 anymore; for any image widgets where they need to fit in a fixed size (such as the sidebar in-game), they need to be scaled down to fit.

This scaling needs to be the same proportion on both axes.

Our sprites also are not guaranteed to be "balanced" for visual weight - some sprites jut off in odd-angles in a way that would confuse a simple/naive centering algorithm. The horsemen are probably a good example of this, because the all carry a lance that juts out to the upper-left, leaving a great deal of empty pixels above them which are nevertheless within the "minimum bounding box containing all opaque pixels".

To counteract this, it may be advisable to ensure that as a sprite is cropped to remove fully transparent margins, that margins in the same dimension are both as small as the smallest one. i.e.
vertical_margin = std::min(top_margin, bottom_margin)

Same for horizontal. This will keep a sprite centered even if it juts off unevenly to just one side.

In the campaign select dialog, the horse icon for the campaign "A Tale of Two Brothers" appears off-center both with respect to the other icons and to the completion wreath surrounding it. See the screenshot.
