I have to apologize, I have only seen the test console once about a
year ago. It has basically been disabled for at least that long. I
think it never got any love because due to prioritization of other
features. I don't know the code that well, so you may need to dig
through the source if want answers. My guess about login issue you
see is that the test console code wasn't updated when we changed how
login worked. It is probably some UX change that needs to happen.
Sorry,
Jason
