nl_tokens: There is - ms - user - select CSS property for IE10 but it seems it works only in desktop browser . So we need to prevent selection event .
pl_tokens: function ( e ) { var srcElement = e . srcElement . nodeName . toUpperCase ( ) , selectableElements = [ 'INPUT' , 'TEXTAREA' ] ; if ( selectableElements . indexOf ( srcElement ) == - 1 ) { return <mask> ; } }
