Solution

  • This appears to be impossible as of IE9 - from How Internet Explorer Chooses Between Document Modes (emphasis added):

    1. In Internet Explorer 9, if the document is hosted in an iframe element, the document mode is determined by the document mode of the top-level webpage. Subdocuments cannot be rendered in IE9 mode unless the top-level document is also in IE9 mode.

    I would assume this rule also applies to framesets - and different document modes - as in your case.

    For a more recent look at how IE11 decides which document mode to render in, take a look at Deprecated document modes and Internet Explorer 11, which contains a flowchart of the process.
