Label support is not complete :)

[wekii]

Hi,

I noticed one small problem with label support in Selectric. If you have multiple inputs and Selectric between them you can not go backward by pressing SHIFT + TAB after Selectric because focus gets stucked on Selectric. When you are going forward by pressing just TAB key than everything works fine.

Also I noticed that label functionality doesn't work on mobile devices if disableOnMobile option is set to false.

Best regards.
