Config Element Counter: Check Boxes Toggle Area Too Big

**addled** ([Bug 58810](https://bz.apache.org/bugzilla//show_bug.cgi?id=58810&redirect=false)):
Clicking anywhere on the UI to the right of the check box and label text for "Track counter independently for each user" and "Reset counter on each Thread Group Iteration" toggle the check boxes.

This makes it fairly easy to accidentally toggle a setting that dramatically changes the runtime behavior of a test plan. It took us a little bit to notice the accidental toggle change.

See attached screenshot. Clicking anywhere in the red area toggles the respective option. Other elements do not work like this.
