The back button does not glow, but instead blinks when tabbed. This happens during initial page load or a hard refresh (ctrl+F5). I have added a data-rel="back" attribute, but the behavior continues. Please see the attached code below.
The native behavior for the back button, I believe, is to glow, and then navigate back. My back button blinks and then navigates back. My back() tap event handler is only a window.history.back() invocation.
Why not remove the event (This might be your issue), and instead use data-rel="back"? You might also try adding href="#" instead of href="". My bet would be on the event and using window.history.back().
