Design Bug: Images Within Wrap-In Box Adds Padding + Background Color

I don't know when this was implemented (I'm currently seeing this on 5.0.4 Beta) but this wasn't occurring before so I imagine this is a recent change... when inserting an image within a wrap-in box, it appears that the image area adds padding and a background color different from that of the wrap-in box. See below:

There should be no padding and no light-navy bgcolor around this image. The image should simply be displayed across the full width of the boundaries of the wrap-in box inner container. It seems to be an issue with the .ipsAttachLink class that is associated with the a href wrapped around the image, as that has padding, bgcolor and border-radius values set against it.

This is the desired appearance of images inserted into wrap-in boxes in this way. The padding, bgcolor and border-radius classes removed from the a href tag, and the border-radius value moved instead into the img tag within the a href.
