Thank you for the screen shots. I tested on my system and see the same behavior in 7.2.1. When I inspect the element, I do not see a click event associated with it. I do see my activity run in my 7.3 system. If you are not able to update to a later release, you can open an SR to see if there is a fix available for 7.2.1.
Here is how the elements were generated in my two systems.
