Hiccup on image zoom when moving cursor away

Hi, all.

I have your typical image-zoom-on-hover transition effect on your typical staff page. However, I’m noticing a slight “hiccup” occurs when you move the cursor away from a headshot image — upon moving the cursor off an image, the whole div appears to grow in size before returning to the normal “none” state.

It may be something I did while trying to figure out how to do the image zoom hover transistion, but I can’t figure it out. Grateful for any help. Share link below.
