I was able to reproduce this on Version 0.99.127.2.2-rc (WebKit 619.1.1). Clicking login on Orion seems to direct the user to http://www.etsyhunt.com/dashboard.
Attempting to login on Safari or Firefox did not warn about the login form being non-secure.
If someone else wants to test, I made a throwaway user:
