title: Tabbed checkbox not working on mobile
body: <p>I am trying to create a TABBED checkbox and everything works fine except on a mobile phone.  On a mobile phone, after I tap one of the tabs, it does nothing, but if I chnage the orientation, then it displays correctly.  Can anyone please help me.  In case it matters, I am testing on an old phone for compatibility, Android 4.4.2.</p>
  
  <p>Here is a codepen with code:
