A11y activated when Prototype.js exists - trashes page style

Description (last modified by bill)

We are finding numerous places where Dojo breaks when Prototype.js is also loaded on a page. This is one example.

The failure occurs in the HEAD version of dijit/_base/wai.js

Here is the code that fails: 

var cs = dojo.getComputedStyle(div);
if(cs){
	var bkImg = cs.backgroundImage;
	var needsA11y = (cs.borderTopColor==cs.borderRightColor) || (bkImg != null && (bkImg == "none" || bkImg == "url(invalid-url:)" ));
	dojo[needsA11y ? "addClass" : "removeClass"](dojo.body(), "dijit_a11y");
	if(dojo.isIE){
		div.outerHTML = "";		// prevent mixed-content warning, see http://support.microsoft.com/kb/925014
	}else{
		dojo.body().removeChild(div);
	}
}

The variable "needsA11y" is getting set to true and the <body> class has "dijit_a11y" appended to it. That triggers major overrides in css - making our page unusable.

We can workaround this by commenting out the line that sets the body class.

I think this is a dup of #7467, which was resolved by fixing dojo.getComputedStyle.
