This was caused by bug 504524.

For some reason after we've added the span to the document, the textnode stays on the overflow list and never leaves it. The fontsize just needs to be big enough to hit some internal limit, for example 10in is big enough, and the quotes don't get any bigger.

Should be fixed by checkin of bug 523468.
