The EasyEdit function is not working when using inside of the ShadowDom, which is needed for Libraries such as Polymer.
Example:
var attachHTML = '<div style="width: 100px; height: 100px; background-color: red;"$CMS_VALUE(editorId(editorName:"test"))$>$CMS_VALUE(test)$</div>';
// Does not work
var div = document.createElement("div");
div.attachShadow({mode: "open"});
var innerDiv = document.createElement("div");
innerDiv.innerHTML = attachHTML;
div.shadowRoot.appendChild(innerDiv);
document.body.appendChild(div);
top.WE_API.Preview.rescan(innerDiv);
// Does work
var div2 = document.createElement("div");
div2.innerHTML = attachHTML;
document.body.appendChild(div2);
It is probably easy to fix this issue by not only checking for some elements children but also for the children of all shadowRoots.
