Right, so after the last PR I tried making the InlineSupportLink work, but there seems to be an issue on build time. The component is imported, but it has nothing in it, and the React devtools says its source is "unknown". Since it does not have a render method on runtime, it leads to the problem that was addressed in the last PR.
I made a test PR to check if the render method would be available on Calypso Live, but it is not.

Since this seems to be a much more complicated issue dealing with how Stats is built, but it has not been resolved, I'm removing it from the parent issue instead of closing it.
