Standby bug on IE9

I found an IE9 only bug with the Standby.js overlay widget. I am using Dojo 1.7.3, but I believe the bug is also on 1.8.3, as the Standby.js file still has the same code. In the _disableOverflow() function, we can see this IE-only code:

if(has("ie") && !has("quirks")){
 // IE will put scrollbars in anyway, html (parent of body)
 // also controls them in standards mode, so we have to
 // remove them, argh.
 if(body.parentNode && &&{
	 this._oldBodyParentOverflow =;
		this._oldBodyParentOverflow = domStyle.set(body.parentNode, "overflow");
		 this._oldBodyParentOverflow = "scroll";
 domStyle.set(body.parentNode, "overflow", "hidden");

In the IE9 inspector, calling domStyle.set(body.parentNode, "overflow") returns a JS associative array, not a string. Later on, on the _enableOverflow() function, that backed-up array is being assigned to, which is expecting a string. The overflow value is kept as "hidden", and that causes the scrollbars to be kept hidden, after the overlay is removed.

A quick fix I made on my code was to change on the _enableOverflow() function: = this._oldBodyParentOverflow.overflow;

Instead of: = this._oldBodyParentOverflow;

And it works.

I'm assume you meant domStyle.get(). So even though the error manifests in dojox/widget/Standby you are saying it's a bug in the core DOM code.

On IE9 I loaded dojo/tests/dom-style.html and then in the console ran:

require(["dojo/dom-style"], function(style){ 
   console.log(style.get(document.body.parentNode, "overflow"));

It works correctly, returning "visible".

Furthermore, I tried dojox/widget/tests/test_Standby.html on trunk, adding a console.log() to the code in question, and when clicking "click to show the Standby overlay on body for 5 seconds", it works fine, and the console.log() prints "visible", not a hash.

That button also works fine on the 1.8 branch, and the 1.7 branch.

Can you provide a test case that's failing? If not, will close as "works for me".
