Editor stays on page if removed quickly enough in AJAX sample which results in two editors on one page

[Jakub Ś]

To reproduce:

1. Put ajax2.html in _samples folder
2. Open it in a browser.
3. Click Create Instance button.

Result:
You will have two editors on page but only one can be hidden/shown.

In ajax2.html I have added this code.

<script type="text/javascript">
	createEditor();
	removeEditor();
</script>

Perhaps this is not very common scenario:) but it is also possible to reproduce it manually. If you click Create and Destroy buttons quickly enough you will get two editors as well (See two_editors.swf).
