The wording in the dialogue that you get when your session is no longer valid (see below) is quite confusing. The message contains a Yes/No-question ("Do you want to save this page as an anonymous user instead?"), but the options are "Dismiss" and "Try again". It's unclear what these buttons will do.
Steps to reproduce:
- Go to a page on https://www.mediawiki.org/.
- Click Edit.
- Change something.
- Log out while still having the edit open (e.g. in another tab).
- Submit changes.
