Inspired by https://www.mediawiki.org/wiki/VisualEditor/Gadgets#Implementing_a_custom_command I was trying to add a `<br />` into the VE using this command:

```

ve.init.target.getSurface().getModel().getFragment().insertContent( [ { type: 'break' }, { type: '/break' } ] );

```

While it actually inserted the line break in visual edit mode, there was not `<br />` in the wikitext after saving the page or switching to wikitext mode within the edit session.

I also tried to implement the whole "command/tool" in an extension, but the behavior was the same. The odd thing is that a `<br />` inserted  in wikitext mode survives the round trip. The linear data model shows it as "alienInline" node then.

Any ideas why the official example didn't work for me?

Greetings,
