This is a simple change and everything works as expected. I tested on a phone, on my laptop in responsive mode, and on my laptop in desktop mode and then shrink the window to responsive mode (where we had an original issue). In all cases, the single response modal closes on first click.

The only thing to note is that this all seems to be working on trunk for me too, so I may be missing something needed to duplicate the issue. Even so, given the safe change and good testing, approved.
