Maximum Resolution for Images: takes lowest value and applies it to both width and height in html output

This is a strange new bug I have not seen in this module before. It now takes the lowest number of the width x height setting and applies it to the HTML output of the field. So I have an image type set to max 210x300 and the output after uploading is:

img src="http://mysite.com/myimage.jpg" alt="image-name.jpg" title="image-name.jpg" height="210" width="210"

The image is actually 3:2 ratio so the incorrect rendered dimensions creates a padding to the left and right of the image. Any idea if this is a bug that crept in to newer release? I have been using various versions of this module for 6-8 months now and have never seen this behavior until installing this release. It normally resizes the image to the max height OR width and then outputs the actual width x height of the final image in the HTML.
