This one should be safe too, unless we're somehow accidentally depending on
elements blurring. I looked through options2 for mentions of 'blur' and nothing
jumped out, plus everything was still working as expected with this change.

         document.activeElement.blur();
     });
   }
   handleWindowBlurs();
