Ah. I just realised that we need to re-initialise the editor in connectedCallback, in case someone disconnects it, and then connects it again (typically if you move the editor around in the DOM). We never do that ourselves, but since it's lime-elements, we need to cover such use-cases anyway.
However, I think we can push that off until after the MVP, so I'll just create an issue for it now.
