PNGs not fixed when dynamically loaded

While working on a View that included transparent PNGs, utilizing the AJAX option, I ran into an issue where the pngFix wasn't being applied to images after using the exposed filter. The pngFix won't work for dynamically loaded images.

I've created a patch that adds the pngFix to Drupal.Behaviors to solve that problem. It's a fringe case but thought someone else may run into this.
