CharacterCount counts non-existing characters

What happens? CharacterCount extension counts non-existing characters.

An empty editor with CharacterCount enabled will show +2 for every newline, and + 4 for every list; even though there are no characters. When adding characters, the count increments on top of those non-existing counted characters.

I haven’t tested “Code” and “CodeBlock”, but I expect a similar result.

Steps to reproduce the behavior:

1. Go to the editor on https://next.tiptap.dev/api/extensions/character-count/
2. On a newline, type "Enter".
3. See count + 2, where it should be + 0.

1. Create a default editor with "Ordered List" or "Unordered List".
2. Add "CharacterCount" extension.
2. On a newline, create a list.
3. See count + 4, where it should be + 0.

Create a new Codesandbox replicating your error Try in the documentation editor: https://next.tiptap.dev/api/extensions/character-count/

What behavior did you expect? Count +0 on newlines and lists.

What’s your environment?

• macOS
• Chrome
• Desktop

Anything else? I haven’t tested “Code” and “CodeBlock”, but I expect a similar result.

Maybe we could add an option { mode: 'nodeSize' | 'textSize' }?

This is used in the Editor too, so that would require us to add the ability to register helper functions through extensions. 👀
