It's not clear to me from the spec how the allowfullscreen attribute
works. It appears to be mentioned only in the security and privacy
considerations section. For example, suppose I have three frames:
Main frame: a.html
-> <iframe src="b.html">
-> <iframe src="c.html" allowfullscreen>
Can c.html go full screen? Where is that specified?
