formElement.submit is not a function

[johnsonc]

Embedded the login form into a template, login popup returns valid accessTokens and status shows connected.
However the per-popup screen keeps waiting and i do not go into the main screen.

browser console:
Uncaught TypeError: formElement.submit is not a function

at v.__wrapper (all.js:90)

at Object.ra [as onMessage] (all.js:85)

I think this is because formElement is pointing to the window, which does not have a submit action. I think the placement of the embeddable code is the culprit AFAICT.

add document.body.appendChild(formElement);
