------- Additional Comments from Dmitry Lomov <dslomov at google.com>
This fix accepts legacy argument order (postMessage(msg, transferables,
targetOrigin)) when third argument is a string.

This is not 100% backward-compatible (previous version was also working for
objects whose toString returned a valid target origin), but I think it is close
enough so as not to break the Internet.
