BUG Resize infinite loops in IE8 (fixes #575)

Browse Source 
IE8 gets a bit confused and fires resize events
when element dimensions in the DOM are changed
as a result of a resize event, causing an infinite loop.
Apart from artificially throttling the event, the only solution
I've found is to check for actual window dimension changes.
http://stackoverflow.com/questions/12366315/window-resize-event-continually-fires-in-ie7?lq=1

This implicitly fixes an issue where TreeDropdownField panel isn't
accessible in the "Insert Media" popup, because the resize event happes
to be triggered by the popup overlay, and in effect closes the drop down
panel right after opening it.

Relating to the jQuery UI component, there's a host of issues and discussions around this, but no solution…
