When a igTree node (version 2017.2) contains text with a single quote in it, the method 'findNodesByText' does not succeed in finding this node.  All other nodes that have no single quote are found successfully.

Example of a node:

<li class="ui-igtree-node ui-igtree-node-nochildren" data-path="23_0_3" data-value="" data-role="node"><a class="onfamilyclick ui-corner-all ui-state-hover ui-state-focus ui-state-active" href="/Catalogus/SearchGroupFam/?GroupNr=71&amp;FamNr=4&amp;Selection=0" style="background-color: rgb(226, 35, 26); color: rgb(255, 255, 255);">AIRCO'S</a></li>

code:

var textToFind = "AIRCO'S";

var nodesFound = $("#igTree").igTree("findNodesByText", textToFind);  <-- nodesFound.length is 0 !

I was able to trace it to the infragistics.ui.tree.js module where the following jquery 'find' command is executed (I have put some space between the quotes and double quotes for clarity):

parent.find(" li > a:contains(' " + text + " ')")

if I use switch the quotes/double quotes around, the node with the single quote is found:

parent.find(' li > a:contains(" ' + text + ' ")')

Is this a bug ?
