I've tried to edit conflict with myself in the Sandbox, but it just overwrote my first change with the second. A demo setup would be helpful.
Help:Paragraph-based Edit Conflict Interface#Usage mentions to enable the beta feature. There's no such option in my Beta Preferences, though according to the roadmap it's still in beta.
Hi @Aron Manning:, thanks for your feedback. Unfortunately, there is no demo setup available for this feature. You can create an edit conflict with yourself if you make one of the changes from a private/incognito window where you aren’t logged in to your account.
Whether the feature is available as a Beta Preference depends on which wiki you are on. On MediaWiki it is a default feature already, so it’s not shown as a Beta Preference in the list. The reason it’s still a beta feature on the roadmap is because it’s currently only a default feature on dewiki, arwiki, fawiki and Group 0 wikis (MediaWiki is in this group). For all other wikis it remains a beta feature for now. --For the Technical Wishes Team

Thank you for the detailed answers. To clarify: this means that if a user conflicts with themself, that case is ignored?
Hi @Aron Manning:, yes, that’s right. But the fact that a user’s conflict with themselves is ignored is not actually something that is decided by this interface. It’s something that the MediaWiki core code does through the “EditPage class”. We didn’t work on that code in this project, so whether an edit conflict is detected and then shown actually depends on the same MediaWiki core code that has been in place for a long time, not on the new paragraph-based edit conflict interface. -- For the Technical Wishes Team
I suspected that is the case. From one aspect it makes sense to avoid complicating editing with conflict resolution with oneself - probably editors just want their last version. Thank you for confirming this.
I'm sorry to hear this is causing confusion. MediaWiki's behavior is underspecified and rather inconsistent when "conflicting with yourself". There are dozens of tickets discussing this problem for years, most notably phab:T36423, phab:T58849, and phab:T222805, as well as very recent incidents, see phab:T246726. When testing the conflict resolution interface it's important to do this with two different users. One of them can be an anonymous, not logged in user, as Max already mentioned. That can be done using an incognito window.
