Idea erased if new user does not have a registered email address

[LanaSina]

How to reproduce the issue:
After writing a New Idea and clicking "save", an error message on the same page asks the user to register an email address. If the user types an address and clicks "save", the email address is registered and automatically redirected to the home page. The idea is not saved and not recorded anywhere; the "your ideas" panel is empty.

After rewriting the idea from scratch, it can be successfully saved.

It's very strange, after creating the idea again and saving it, I get a link to the saved idea. But it still does not appear in the "your ideas" panel:

Yet the link to the saved idea, which I bookmarked, does show my saved idea. Where can I go to see all my unpublished drafts?

Is there any additional info I could provide to help?
