robot test repeating problem (IE8)

[bill]

I'm getting a problem that when Dialog_a11y.html or Dialog_mouse.html run (and probably other tests too) on my IE8 machine, it runs the test twice (reporting the results twice too). I traced this much:

There's an <input> in runner.html:

<input type="text" tabIndex="-1" style="border:0px
none;margin:0px;padding:0px;position:absolute;left:0px;top:0px;width:200px;height:42px;background-color:white;z-index:9999;opacity:0;filter:alpha(opacity=0);cursor:default;"
	onmousewheel="_onmousewheel(arguments[0])"
	onmousedown="_onmousedown(arguments[0])"
	onkeypress="_onkeypress(arguments[0])"
	onfocus="_onfocus(this)"
	onblur="_onblur(arguments[0])">

When I load the page (hitting the refresh button on the browser), the onmousewheel handler fires. Not sure why, since I didn't move the mouse wheel. Anyway, that calls doh.robot._onKeyboard(), and that does the setTimeout:

	setTimeout(function(){
	        var rf = document.getElementsByTagName('input')[0];
	        rf.style.visibility = "hidden";
			doh.robot._run(window.frameElement);
	}, 0);

Then the timeout fires, and doh.robot._run() is called, which calls doh.run().

That makes the test suite execute. doh.run() is actually called repeatedly, apparently because of all the deferreds (the test is paused then resumed at each deferred I think), but that seems normal.

The problem is that after (what should be) the final doh.run() completes, and the results are reported... that's when _initRobot() gets called. Apparently that's supposed to get called first, right?

_initRobot() calls doh.run() which then runs the entire test suite over.

Apparently this bug only occurs when the IE8 developer toolbar is turned on. (The debugger doesn't have to be running, just the DOM inspector thing.)

Anyway, I checked in a change in [17226] so _initRobot() only runs once, and that seems to solve the problem.
