>From the current spec text, it's not clear that window.showModalDialog( )
should be blocked inside a sandboxed iframe. It seems that it should follow in
the same suit as window.open(). 

showModalDialog() should be added to the sentence "This flag also prevents
content from creating new auxiliary browsing contexts, e.g. using the target
attribute or the window.open() method." [1]

Additionally, in the steps for executing showModalDialog [2], the first step
should indicate that the UA should abort these steps if the "sandboxed
navigation browsing context flag" is set.
