Based on the conversation at https://bugs.webkit.org/show_bug.cgi?id=95890#c3, I believe that the expectation in `fast/frames/seamless/seamless-inherited-document-style.html` regarding `-webkit-user-modify` is incorrect. We don't want to inherit `-webkit-user-modify` from the IFrame, for the same reasons that we don't want to inherit the `contenteditable` attribute.

I'm comfy with this change. :)
