Description Chris Dumez 2015-09-12 15:31:05 PDT
Document.title does not behave according to specification:
https://html.spec.whatwg.org/multipage/dom.html#document.title

In particular,
1. Adding a title element to the Document does not always update the value returned by document.title even if the element if the first title element in the document.
2. The *first* title element in tree order is supposed to update the document title. However, in WebKit, it is the first title *added* to the document, even if it is not the first in tree order.

Nit: we shouldn't have curly brackets around a single line statement.
