I think that it might be related to

In IE9 it's not good idea to mix quirks and standards pages (iframes), because they won't behave in the way that it's expected, and IIRC, even some js tests will fail stating that the rendering is done for example in standards mode but the reality is that they have been forced to quirks (or the other way around).

There's no reason to use Quirks mode except while supporting very old sites, and in those sites the developer can add the X-UA-Compatible header (and forget about using code with new features)
