When using html Tags inside the property defined as itemData the item is not selectable.
var tf = new Tokenfield({
el: document.querySelector('.my-input'),
itemData: 'data',
items: [{id: 1, name: 'foo', data: 'foo <b>Something important</b>'}, {id: 2, name: 'bar', data: 'bar <b>Something important</b>'}]
});
If you click on "Something important" nothing happens. Clicking on foo or bar works though as it is not wrapped in a tag I guess.
