If you embed an iFrame on a webpage, and you click forward to some other page; once you hit the back button and reload the first page, the iframe is duplicated among all iframes. 

e.g. on example URL, scroll down, note the two youtube videos, click a link, and then go back. The video is now duplicated, or the first video is missing.

I could only reproduce missing first video in Safari 7.1, never a duplicated one. The missing video issue occurs most of the time, but not 100%.

It seems like a real bug - there is an honest <iframe src="http://www.youtube.com/embed/W7tj1vRDtUw">, which remains blank. Instead of a plug-in document, we have an empty document here.
