loadTagNamespaces in /libs/cq/tagging/widget.js is loading the tagNamespaces wrongly when I give tagsBasePath as /etc/tags/facebook/work for xtype:tags?

Hello Team,

I have a requirement to show up the tags only for tag path /etc/tags/facebook/work. I played with tagsBasePath as /etc/tags/facebook/work to get only facebook work tags displayed. But when I click on the tag to get added, tag is not getting added. When I digged into the code, I am seeing the following error. I am not sure If I should not change the tagsBasePath and please help me how to achieve my functionality.

1. Uncaught TypeError: Cannot read property 'name' of undefined widgets.js:1573

 loadTagNamespaces: function() {

        this.tagNamespaces = {};
        var tagJson = this.loadJson(this.tagsBasePath + CQ.tagging.TAG_LIST_JSON_SUFFIX + "?count=false");
        if (tagJson && tagJson.tags) {
            CQ.Ext.each(tagJson.tags, function(t) {
                this.tagNamespaces[t.name] = t;
            }, this);
        }

         this.setupPopupMenu();

        this.tagNamespacesLoaded = true;
    }

facebook:work/employer/305115773870 -- nsTagId

getNamespaceDefinition: function(nsTagID) {
        if (!this.tagNamespacesLoaded) {
            this.loadTagNamespaces();
        }
        
        var nsName = CQ.tagging.parseTagID(nsTagID).namespace;
        return this.tagNamespaces[nsName];
    }

Here as a result : I am getting the getNamespaceDefinition function returning the value as undefined.

checkMaximum: function(tag) {
        var ns;
        
        if (typeof tag === "string") {
            // new tag
            if (this.displayTitles) {
                ns = this.getNamespaceDefinitionByTitlePath(tag);
            } else {
                ns = this.getNamespaceDefinition(tag);
            }
        } else {
            // existing tag
            ns = this.getNamespaceDefinition(tag.tagID);
        }
        
        if (ns === null) {
            // if the namespace is not found, we can't change for a maximum and have to accept it
            return true;
        }
     
        var cfg = this.getNamespaceConfig(ns.name); -- ns.name of undefined is giving the above error for which I have provided the stack trace.

...

}

values that I got out of debug:
