If you want to do this, you would need to re-upload an error screenshot with the correct line number. Consistency in content is more important than consistency with the external code example, because that one may be constantly updating.

The code example is not properly formatted. Maybe you would want to run Prettier on that HTML so we never have to update the line numbers again, or perhaps we would wait for someone else to do that. Otherwise if we re-format that code one day, we would have to do this all over again.

@RasmusKard It looks like we are currently doing a big audit over all external examples, so I'm closing this for now. The content itself makes sense and we will make sure the external example is itself stable before updating content.
