html.html attr_map, attr_reconnect test failures on IE8

[bill]

IE8 and perhaps other browsers/browser versions get intermittent failures on the attr_map and attr_reconnect tests. I finally figured out that the problem happens if the test is run while the browser is minified.

    _AssertFailure: assertEqual() failed: 	expected
		2
	but got
		1

 with hint: 
		onfocus ctr == 2
     ERROR IN: 		 function attr_map(t){
							var input = document.createElement("input");
							var ctr= 0;
							dojo.attr(input, {
								"class": "thinger blah",
								"tabIndex": 1,
								"type": "text",
								"onfocus": function(e){
									ctr++;
								}
							});
							dojo.body().appendChild(input);
							doh.is(1, dojo.attr(input, "tabIndex"), "tabIndex");
							if(!has("ie") || has("ie") > 7){
								// IE6/7 treats type="text" as missing, even if it was
								// explicitly specified
								doh.is("text", dojo.attr(input, "type"), "type");
							}
							doh.is(0, ctr, "onfocus ctr == 0");

									doh.is(2, ctr, "onfocus ctr == 2");
								}), 10);
							}), 10);

I have a fix, I'll checkin.

In [27811]:

Fix IE spurious test errors in attr_map, attr_reconnect when browser window is minimized. FF still fails though. Fixes #14760.
