Description
In wicket-event-jquery.js starting with Line 115 the method isIE11 does not return a boolean.
Current implementation:
var isTrident = userAgent.indexOf("Trident");
var is11 = userAgent.indexOf("rv:11");
Fix:
var isTrident = userAgent.indexOf("Trident") > -1;
var is11 = userAgent.indexOf("rv:11") > -1;
