REGRESSION(84329): Stylesheets on some pages do not load

Repro:
1. Go to http://www.tbray.org/ongoing/When/201x/2011/05/23/Intimations

The page should render like it does in other browsers. Instead, it shows up without stylesheets.

I bisected, and this is caused by r84329

(This is also http://crbug.com/83786)

Clicky: http://trac.webkit.org/changeset/84329

function setActiveStyleSheet(title) {
    var i, a, main;
    for (i=0; (a = document.getElementsByTagName("link")[i]); i++) {
    if (a.getAttribute("rel") &&
            a.getAttribute("rel").indexOf("style") != -1 &&
            a.getAttribute("title")) {
        a.disabled = true;
        if(a.getAttribute("title") == title) a.disabled = false;
    }
    }
}

FYI, the page works fine on other browsers.

Also if you click on the 'Sans Sherif' link, this calls the function ap mentioned but the style is applied correctly. It is only the 'Sherif' style sheet (the default one) that is not applied properly. I think this should be investigated before closing.

No, definitely not. This snippet looks correct.

Does that mean that http://trac.webkit.org/changeset/84329 incorrectly implemented what HTML5 says to do, or that the behavior that HTML5 specifies is inconsistent with what other browsers do and incompatible with the web?

I am still investigating the issue but I lean towards an incorrect implementation in this case.
