Making the Lightning Inspector work on a Lightning Component presented in a Visualforce page

Question

I have the Salesforce Lightning Inspector Chrome extension installed and this works when Lightning Experience is turned on.

But when testing in Salesforce Classic where a Lightning Component is added to a Visualforce page via $Lightning.use, it generates this error:

Uncaught TypeError: global.$A.getContext is not a function

with a link to this fragment of code:

// Since we were injected, Aura could already be available. If so, let the devtools know.
if(!global.$A || !global.$A.getContext()) {
    var _Aura;
    ...

Is there a way to make the Lightning Inspector work for this case?

As of 4 Apr 2017 it is now working. May be something I've changed in my code or something changed in the platform.
