So I was loading the review panel over and over out of boredom and happened to notice that some of the profile picture squares were different than others when the image hasn't loaded yet:
Am I supposed to play hopscotch here?
So, at first curious what was up, I inspected the HTML to compare them, and there's quite a few differences:
Profile pictures don't get the
width="32" height="32"part on the image itself.
Gravatars get an empty
classattribute, missing the
gravatar-wrapper-32class. Weird that the Gravatar class would be applied to the non-Gravatar images.
To show this issue in a brighter light, this greatly impacts profile pictures which have a transparent background. A picture (with a transparent background) uploaded to Gravatar would appear with a white background, and uploaded directly as a profile picture would have the blue background, as seen here:
They really should have consistent display.
