I have created an editor via:

```auto
let editor = new Editorview( ... )

```

and everything works fine.

I try to set a theme using `editor.setOption('theme', 'blackboard');`  
and it appears nothing happens.

From googling around, it appears this is the CodeMirror5 way of doing things.

In CodeMirror6, how do I set my theme to ‘blackboard’ (or any black-background theme?)

[The configuration example](https://codemirror.net/examples/config/) (specifically the section about dynamic configuration) should help.
