a_attr and li_attr not adding attributes

[rupisaini123]

I am passing in additional attributes for a and li tag using data-jstree. But these attributes are not added to these elements.
Here is my sample HTML:
`

Administration

`

Here is the rendered HTML
` <li
role="none"
data-jstree='{"selected": true

,"disabled": false 
,"a_attr": {"title":"Tooltip for Node 1","class":"testttt"}

,"li_attr": {"title":"Tooltip for Node 1","class":"testttt"}

}'
id="Pages.Administration"
class="jstree-node jstree-open"
>

Administration




<li
role="none"
data-jstree='{"selected": true

,"disabled": false 
,"a_attr": {"title":"Tooltip for Node 1","class":"testttt"}

,"li_attr": {"title":"Tooltip for Node 1","class":"testttt"}

}'
id="Pages.Administration.AuditLogs"
class="jstree-node jstree-leaf"
>

Audit logs

`

Code for initialization
`var _jsTreeOptions = {
types: {
default: {
icon: 'fa fa-folder text-warning',
},
file: {
icon: 'fa fa-file text-warning',
},
},
checkbox: {
keep_selected_style: false,
three_state: false,
cascade: '',
},
search: {
show_only_matches: true,
},
plugins: ['checkbox', 'types', 'search'],
};

  if (options) {
    if (options.singleSelect && options.singleSelect === true) {
      $.extend(_jsTreeOptions, {
        core: {
          multiple: false,
        },
      });
    }
  }

  $tree.jstree(_jsTreeOptions);`

I am not sure what exactly i am missing.
