#qunit-fixture should define a width and height

[gnarf]

I just ran into a lot of hell trying to test animations because the width of the element I was animating wasn't what I had defined it (in IE7):

Just adding width: 1000px; height: 1000px; to the #qunit-fixture in my CSS fixed the issue on my test page

Landed. This may have unintended consequences on other existing testsuites, though generally the element isn't in the viewport and its dimensions shouldn't matter, so...
