doesn't seem related to magic iframe. 

However, I'm not sure what to deduct from what I see, maybe this will help Eric: it appears that iframe element gets a renderer before it gets insertedIntoDocument() call, then the whole fragment gets inserted into a document... Here is the callstack where IFrame gets the renderer:
