'wakeOnTouch' for Bangle.js 2

With your suggestions above, I've got a working solution :

Bangle.setOptions({wakeOnTouch:true});

Bangle.on("touch", function(b, xy) 
{
  console.log("main - touch",b,xy, Bangle.isLocked());
});

But it looks like, when in locked state, I have to tap twice - not a 'double tap', but tap - wait - tap :

Or is this normal behavior ?
