Bangle 2: LCD backlight behaviour

The one called "Bluetooth Widget" in the App loader. I think line 10 is to blame:

WIDGETS["bluetooth"]={area:"tr",width:15­,draw:function() {
  g.reset();
  if (NRF.getSecurityStatus().connected)
    g.setColor((g.getBPP()>8) ? "#07f" : (g.theme.dark ? "#0ff" : "#00f"));
  else
    g.setColor(g.theme.dark ? "#666" : "#999");
  g.drawImage(atob("CxQBBgDgFgJgR4jZMawfAc­A4D4NYybEYIwTAsBwDAA=="),2+this.x,2+this­.y);
},changed:function() {
  WIDGETS["bluetooth"].draw();
  Bangle.setLCDPower(1); // turn screen on
}};
NRF.on('connect',WIDGETS["bluetooth"].ch­anged);
NRF.on('disconnect',WIDGETS["bluetooth"]­.changed);
