Bug: Writing an answer when logged out and then logging in doesn't save the answer!

This scenario works fine for questions:

1. In logged out state, try to ask a question
2. It asks to login
3. After login, the question form is pre-filled from what was entered before.

It doesn't work for answers! I wrote an answer when logged out and it was lost because it didn't save it during login:

1. In logged out state, try to post an answer
2. It asks to login
3. After login, the answer is not pre-filled in.

Pretty sure it's a bug.
