I'm trying to include a cc address for my item list email link.

I used this:

     "href": {
          "operator": "+",
          "operands": [
            "mailto:",
            "[email protected]",
            "?cc=",
            "[email protected]",
            "?subject=",
            "Test Subject",

The result is the following:

[![cc][1]][1]

For some reason my subject lengthens the cc field. Any idea what goes wrong here? 

If I look at the code I don't see anything wrong.
