Area type with a mysterious background
Ran across something I've never seen in Illustrator before and that I cannot wrap my mind around, perhaps somebody has any ideas.
Have a look at this simple ai file with one area type object with a mysterious gray background box, which apparently comes out of nowhere. It's not a fill or stroke, it's not an effect, in fact, it's not visible in the Appearance panel at all. If I Clear Appearance it persists. It's also not an artboard. If I Expand it or add anything new to the Type object (fill, stroke, effect) then the background disappears, but I can copy it to a new document and resize it all I want and the background persists and the text flows within it just normally.
Is there some hidden Area type option that I'm not aware of? Or has this to do with some scripting? Or is it just a bug? Anyone have any ideas what's going on here?
