lang-html is not highlighting

I read the documentation, I read the source code, and I am getting no syntax highlighting.
I am creating the editor like this:

EditorState.create({
          doc,
          extensions: [
            history(),
            keymap.of([...defaultKeymap, ...searchKeymap, ...historyKeymap]),
            defaultHighlightStyle,
            html(),
            lineNumbers(), gutter({ class: 'cm-mygutter' }),
            search({ top: true })
          ]
        })

What’s the totally obvious think I am missing?

Cancel that. I found the issue
