This is so that commands in user agents that should only be contextual to markup documents do the right thing when a Web Archive is displayed.

It would be nice to know if there are any serious implications from this change.

One more concern. You said this was a regression. What was the commit that it regressed in?

I believe it was a regression from WebKit1 to WebKit2.

I’m not sure this patch is right. Can’t a web archive be created with contents that are not HTML, SVG, or XML? In that case, this function would return the wrong thing. I think in the case of the web archive we need an “internal MIME type” to correctly implement this function.

This version might be OK for now, but there is a chance that it has some edge cases wrong.

Yeah, I guess we need to see if the web archive has an item that we'd load as html or svg.
