Auto logout causes ckeditor to detach when editing a page

Problem/Motivation

When editing pages using ckeditor the editor with run its detach function due to the ajax call to autologout_ahah_set_last. It looks like this is due to the timer element not being present on the page so drupal ajax is running detachBehaviors on the document and not scoped to the timer element.

Steps to recreated:

• Set auto logout timeout to 60 seconds for ease of testing
• Create or edit a basic page using the ckeditor
• Wait for 60 seconds – a request to autologout_ahah_set_last should be made
• When the response is received Drupal won’t find the an element with the id #timer
• detachedBehaviours will run scoped to the document and ckeitor will disappear showing the raw markup

Proposed resolution

Insert correct markup using javascript to the page and modifying the response received to contain the correct markup

Remaining tasks

Create patch for review
