When top of button is clicked, it moves out of the way. #3
Description
See here, I guess it's getting moved a bit lower during the :active state so it actually is no longer getting a click, or at least the cursor is changing to not be a pointer anymore.
Just pointing it out since we had trouble with some buttons doing this. One solution is to add a pseudo :after element to the button in CSS that is absolutely positioned and goes above the top of the button so it accommodates that.
