hideOnWindowScroll doesn't work

[NordlingDev]

This setting does not work. I've set it to false and yet when I scroll the window, it will hide itself.

This is my code: $('select').selectBox({ mobile: true, menuTransition: 'default', hideOnWindowScroll: false });

I've tested this on my phone with Dolphin Browser and Chrome (Android) and on my Mac with Firefox and Chrome.
