Edits are lost after user logins in

[suhasm]

To reproduce:

1. Stay logged out, and edit a page
2. Save changes. You will prompted to login.
3. You login, but your edits are lost.

Suggested fix: Lock the editor unless logged in.

Our paid proofreader lost 2 pages of work due to this yesterday (I think). We may have unwittingly lost more in the past.

Currently we have this banner at the top for anonymous users:

But perhaps it's not clear enough, or maybe it's a case of banner blindness.

Options are:

1. Lock the editor.
2. Warn more aggressively once content is changed.
3. Keep edits even after login.
4. Allow anonymous contributions

(3) is proper but I need to research how to do it. (4) is risky without better moderation and monitoring tools. (2) could be done well, I think. (1) is the easy fix, but I also want anonymous users to be able to play around with the editor and get a sense of what it's like.

What do you think about (2)?

2 is fine, though I think we should also disable the save changes button. We don't want it redirecting to the login page without saving subsequently.

Sounds good -- I'll make the change.

Fixed by disabling the submit button.
