I don't have a proposed solution so far.  I just have a problem.  The 
problem is that UAs that implement <iframe srcdoc> per spec end up with 
broken UI.  Safari certainly does, and so will Firefox with the current 
srcdoc patches.

Generating an equivalent data: URL may not be good enough as a solution, 
because that would require teaching all sorts of extensions and other 
code that assumes that loading a url will give you the data about this 
special case.

Having the url of the document end up something like about:srcdoc?abcdef 
where dereferencing it gives you the right data _may_ be a solution.

But again, I don't have a solution so far, just the spec as-is causing 
obviously broken UAs.
