I've just confirmed in Chrome that neither `"from document"` nor `fromdocument` work, and filed an entwine issue: https://github.com/hafriedlander/jquery.entwine/issues/24

In the meantime, I've solved it as follows:

```js
(function($) {

	// Temporary workaround until entwine supports 'from document'
	$(document).on('context_show.vakata', function(e) {
		console.debug('aaa');
		$('.cms-tree').trigger('context_show_custom', e);
	});

	$.entwine('ss.tree', function($){
		$('.cms-tree').entwine({
			oncontext_show_custom: function(e) {
				this.adjustContextClass();
			},
```

Naomi, could you test this solution works for you on IE?
